Origami Burr Puzzle (Froy)

Origami Burr Puzzle (Froy)


Hey guys, this is Evan from EZ Origami,
and today I’ll be teaching you how to fold an origami Burr Puzzle designed by Froy. This is one of my
all-time favorite modular models, and it’s not very difficult to fold. This
model requires six square sheets of paper. Each unit is folded from one
square, and I recommend using six inch squares to fold the units. Using six inch
squares will result in a model about three and three-quarter inches wide. I also recommend using thicker paper to
fold this model. Papers such as Tant and Elephant Hide will work well, but if you
decide to use something more common such as copy paper or kami, smaller squares
will work best. And once you’ve prepared your paper then
we’re going to start with our first square with the colored side up. And
we’re going to start by folding in half diagonally, so take this bottom right
corner and fold it up to the top left corner. Align the corners and the edges,
then make your crease, and then unfold. And now we’re going to rotate the paper
so that the crease we just made now runs from the top left corner down to the
bottom right corner. And then we’re going to fold in half diagonally in the
opposite direction. So once again, take this bottom right
corner and fold it up to the top left corner. Align the corners and the edges, and make
your crease, and then unfold. Now we’re going to turn the model over,
and then we’re going to rotate the paper so that one of the diagonal creases we
just made is now held vertically. And from here we’re going to make two small
reference creases by folding these two edges in to align with this vertical
crease. So we’re going to start with this bottom right edge here, and we’re simply
going to pick it up and pull it over to the left, towards the center of the model.
Then we want to start at the bottom of the model and work our way up, aligning the edge with that crease. Just
like this. And once everything is aligned, then we’re not going to crease all the
way. You just want to make a small reference crease on the top of this
colored edge here, just like that. And once you made that
small reference crease then you can unfold. And now we’re going to do the
same thing on the left. So we’re going to start with this bottom
left edge here, and once again we’re going to pick it up and pull it over to
the right towards the center of the model. Then you want to start at the
bottom of the model and work your way up, aligning the colored edge with that
vertical crease. Just like this. And once everything is aligned we’re not going to
crease all the way. We just want to make a small reference crease on the top of
this edge here, just like this. And once you
have that small crease then you can unfold. Now we’re going to rotate the paper just
like this so that there’s now a reference crease on the right and the
bottom edges of the paper. Now we’re going to fold up this bottom
edge and align this small reference crease with this crease intersection
here. So we’re going to do that by simply pulling up the bottom edge, just like
this. And once that small reference crease is aligned with that crease
intersection, then you can make your crease all the way across. Just like that. And once you’ve done that,
then your model should look like this. Now we’re going to fold down this top
edge and align it with this colored edge here. So we’re going to do that by simply
pulling down the top edge, just like this. And then you want to align the two
colored edges of paper in the center of the model, and then you can crease all
the way across. Just like that. And once you folded in
both sides, your model should look like this. And now we’re going to unfold the two
colored flaps that we just folded in. And now you’ll see that you’ve added
these two parallel creases here. And now we’re going to make two parallel creases
in the opposite direction. So before we do this, you still want to
make sure that there’s a reference crease on the right and bottom edges of
the model. And then we’re going to start by folding in this right edge and we’re
going to align this right reference crease with this central crease
intersection here. So start by pulling the right edge over
to the left, just like this. And again you want to align that small
reference crease with that crease intersection. And once everything is
aligned, then you can make your crease. And now we’re going to fold over this
left edge and align it with this colored edge here. So we’re going to do that by
pulling the left edge over to the right, just like this. And then you want to align
the two colored edges in the center of the paper. And once everything is aligned,
then you can make your crease all the way across. And once you folded in both
sides, your model should look like this. Now we’re going to unfold the two-color
flaps that we just folded in. And then we’re going to rotate the paper, just
like this, so that the two reference creases are now held on the bottom of
the model. Now we’re going to fold along existing creases. So we’re going to start by folding over
this bottom right edge along this parallel crease that we just made. So we’re going to do that by simply
pulling the bottom right edge over to the left, along that existing crease. Then
your model should look like this. And then we’re going to fold in this bottom
left edge along this parallel crease that we made before. So we’re going to start by pulling the
bottom left edge over to the right, just like this. But then you’ll see that the crease
doesn’t go all the way to the bottom. So what you want to do is introduce a new
crease by simply creasing across all layers, but you also want to make sure
that the paper doesn’t drift. So just be careful while you’re making that crease,
and once you’ve done that to both sides, your model should look like this. And now we’re going to focus on the
bottom portion of the model here. And now we’re going to fold up this bottom
corner and align it with this point here where these two colored edges meet. You will
also see that the small reference creases come together at that same point. So what we’re going to do is simply pick
up the bottom of the model and align that bottom corner with the crease
intersection that I mentioned before. And once everything is aligned, then you can
crease through all layers. And then your model should look like this. And
then we’re going to unfold the bottom corner that we just folded up. And then
we’re going to unfold the two flaps that we folded in before. And once you’ve
done that, you’ll be able to see the new creases that you just introduced. Then
from here we’re going to rotate the paper so that the new creases are now
held on top. And then we’re going to do the same thing on the bottom. So again
we’re going to start by folding in along existing creases. And we’re going to start by folding this
bottom right edge in along this parallel crease here. So we’re just going to fold
over the bottom right edge, just like we did before, along that existing crease. And then
we’re going to fold over this bottom left edge along this parallel crease
that we made before. So once again we’re going to pull the
bottom left edge over to the right, just like this. And then you’ll see that the
crease doesn’t go all the way across, so you’ll have to introduce a new crease
on the bottom of the model here. But once again you want to be careful while
you’re making this crease just so that the layers don’t drift out of place. So once you folded in both sides, then
your model should look like this. And again we’re going to focus on the
bottom of the model here. And then we’re going to fold up this bottom corner and
align it with this point here, where these two colored edges intersect. So again we’re just going to pick up
this bottom corner, and we’re going to pull it up and align it with that
intersection. Just like this. And once everything is aligned, then you can make
your crease through all layers. And then your model should look like this. And once again we’re going to unfold the
bottom corner that we just folded up. And then you can unfold the two colored
flaps that we folded in before. And once you’ve introduced those new creases on
both sides, your model should look like this. And now we’re going to focus on the
bottom of the model here. Now we’re going to fold up this bottom corner along this
small horizontal crease that we made before. So we’re going to do that by
simply pulling up the bottom corner just like this, and we’re going to fold it up along that
existing crease. Then you want to reinforce that small horizontal crease,
but you’re not going to crease all the way across. And at this point the model
will not lie flat. So we’re simply going to collapse along
existing creases, just to flatten it out. So we’re going to start with this right
edge and we’re simply going to fold it in along this existing crease here. And I
suggest that you hold the paper down flat towards the center of the model.
Then what we want to do is take this right edge, and we’re simply going to
push it over to the left towards the center of the model just like this. And as you’re doing this you’ll see that
the paper will collapse along that existing crease. Then we simply want to
flatten it out, just like this, by introducing a new crease here. And
then we’re going to do the same thing on the left. So we’re going to fold in this left edge
here, along this existing crease that we made before. Again I suggest you hold the paper down
flat, towards the center of the model. And then what we’re going to do is push this
left edge over to the right towards the center of the model, just like we did on
the other side. Again you’ll see that the paper will collapse along this existing
crease, and then we’re just going to flatten out the rest of that flap by
introducing a new crease here. And once you’ve done that on both sides, your model should look like this. And
then we’re going to unfold all of the colored flaps that we just folded in so
that we’re back to the original square. And then we’re simply going to rotate
the paper so that those new creases we just made are now held on top. And then
we’re going to do the same thing. So we’re going to start by folding up
this bottom corner along this small horizontal crease. So just pull up the
bottom corner, like this. And then we’re going to reinforce that small horizontal
crease, just like we did before. And once again you’ll see that the model does not
lie flat. So we’re going to start with this right
side here, and we’re going to fold in this right edge along this existing
crease here. So again I suggest that you hold the
paper down flat towards the center of the model. Just like this. And then we’re
going to push this right edge up and over to the left so that it collapses
along this existing crease here. Then what you want to do is simply
flatten out the rest of that flap by introducing this new crease here. And
once you’ve done that on the right, then we’re going to do the same thing on the
left. So we’re going to fold in this left edge
along this existing crease just like we did before. Once again I suggest you hold the paper
down flat towards the center of the model. And then we’re going to push this
bottom left edge over to the right towards the center of the model, just
like we did before. Again you’ll see it collapses along
this existing crease. Then you simply want to flatten out the rest of that
flap, just like this, by introducing that new crease there. And
once you’ve done that on both sides, your model should look like this. And once again we’re simply going to
unfold the colored flaps that we just folded in, so that we’re back to the
original square. And now you’ll see that you’ve added these new creases here. And
now we’re going to fold the model in half along this existing horizontal
crease here. So we’re going to do that by simply picking up the model from both
sides. And then we want to make that crease a mountain fold, so we’re simply
going to pinch the model from the top, just like this. So that we fold it in half
along that existing crease. And then you can put the model back down flat. And then
you should have this. And now we’re going to focus on the top left corner of the
model here. And now we’re going to make a new crease that extends between this
crease intersection here, and this reference crease on the bottom of the
model. And I find that the easiest way to do this is to fold this left corner over
to the right along this existing crease here. So we’re just going to pull the
left corner over to the right, along that existing crease. And then you should have
this. And then we want to use this top crease intersection as our pivot. So you
just want to hold the layers down flat on the top of the model, then we’re going
to pull this flap over to the right, just like this. And once this edge reaches
that small crease intersection on the bottom of the model, that’s when you can
make your crease. So just crease through all layers, just like this. And then your
model should look like this. And now we’re going to fold up the
bottom edge of the flap that we just folded over, and we’re going to align it
with this left edge here. So we’re just going to pull up this bottom edge, just
like this. And we’re going to start at this bottom point here, and we’re going to
work our way up aligning both of those edges. Just like
this. And once everything is aligned, then you can make your crease. And now you’ll
see that the top of this flap extends past the top of the model. So what we’re going to do is simply lift
up the model like this, and we’re going to fold that small flap behind. So just
fold it back like this, and then we’re going to crease through all layers. And
once all the layers on the top are aligned, then you can unfold that small
flap that we just folded back. And now we’re going to fold this flap over to
the left, along this existing crease here. So we’re going to do that by simply
pulling the right side of this flap over to the left, just like this. And once the
right edge is aligned with that crease that I mentioned before, then you can
make your crease through all layers. Just like this. And once you have this, then we can
unfold the small flap that we just folded over. Then we’re going to grab this
corner on the top of the model and we’re going to pull it to the left as far as
it will go, just so that we unfold the left side of the model. And once you have
this, you’ll be able to see all the new creases that we just made. And once you
have this, then we’re going to turn the model over and we’re going to do the
same exact thing. So once again, we’re going to focus on
the top left corner of the model. So again we’re going to start by making
a small crease here. But this time you’ll notice that there is no small reference
crease. So what we’re going to do is make our
crease between this crease intersection here and this point here, where this
crease intersects with this bottom edge. So again I find it easiest to fold this
left corner over to the right, along this existing crease. So we’re just going to fold
the left corner over, just like we did before. And then we’re going to use this
top point as our pivot, so just hold the layers down flat. And again we’re going
to pull this flap over to the right, just like this. And once this edge reaches the
crease that I mentioned before, then you can make your crease. Just like this. And
then your model should look like this. And now we’re going to fold up the
bottom edge of this flap that we just folded over, and we’re going to align it
with this left edge here. So we’re going to start by lifting up this bottom edge.
Then we want to start at this bottom point here, and work our way up, aligning both of the edges on the left
side of the model. Just like this. And once everything is aligned, then you can
make your crease. And once your model looks like this, then you’ll see that
small point that extends past the top of the model. And again we’re just going to pick
the model up, and we’re going to fold that small point behind as far as it’ll go. Just like this. Then you can make your
crease through all layers. And then all the layers on the top of the model
should be aligned. And now we’re going to unfold the small flap that we just
folded behind, and then you’ll be able to see the small crease that we just made.
And now we’re going to fold this flap over to the left, along this existing
crease here. So we’re going to do that by simply pulling this flap over to the
left, just like we did before. And once the edge of the flap is aligned with
this existing crease, then you can make your crease through all layers. Just like
this. And once you have this then we’re going to
unfold the small flap that we just folded over. And then you want to grab this
point at the top of the model and we’re going to pull it over to the left as far
as it’ll go so that we unfold the left side of the
model. And once you’ve introduced those new creases on both sides, your model
should look like this. Now we’re going to unfold the model so
that we’re back the original square. So we’re just going
to pick up the paper from both sides, and we’re going to release that layer from
behind. And then your model should look like this. And now we’re going to focus on the
bottom portion of the model here. And we’re going to fold up the bottom of the
model by making a new crease that extends between this point here, where
these three creases intersect with this right edge, and this point here, where
these seven creases intersect. So we’re going to start by lifting up
this bottom edge, and we want to start our crease at this point where those
three creases intersect. So you just want to hold down the paper
at that point, and then you want to pull the paper up, just like this, until it
reaches this point here where those seven creases intersect. So once this edge is aligned with both
of those references, then you can make your crease all the way across. And once
you have this, then we’re going to rotate the paper so that the flap we just folded
in is now held on top. And then we’re going to do the same thing on the bottom
of the model here. So once again we’re going to fold up
this bottom edge by making a new crease that extends between this point here,
where these three creases intersect with this right edge, and this point here,
where these seven creases intersect. And we’re going to start our crease at this
point here. So you just want to hold the paper down
where those three creases intersect, and then we’re going to pull up the colored
flap, just like this, until this edge reaches this point here, where those
seven creases intersect. So once this edge is aligned with both
of those references, then you can make your crease all the way across. Just like
this. And once you’ve done that on both sides,
your model should look like this. And then we’re going to turn the paper over.
Now we have finished all of the pre-creasing for this model. So from here on out I’ll just be marking
the creases that we will need for each step. And we’re going to start by reinforcing
these four creases that I’ve marked here. And we want to make sure that each of
those four creases is a valley fold. So we’re going to start with this bottom
left crease here. And what we’re going to do is simply pick up the right side of
the model, and then we’re going to reinforce that crease from underneath.
Just like that. Then you can put the model back down. And then we’re going to
do the same thing with this bottom right crease here. so we’re simply going to
lift up the right side of the model, and we’re going to reinforce that crease
from underneath, just like that. And then you can put it back down. Then we’re
going to rotate the paper, so that the creases we just reinforced are now held
on top. And then we’re going to do the same thing with these bottom two creases
here. So once again we’re going to start with
this bottom left crease here, and we’re simply going to lift up the right side
of the model, and we’re going to reinforce that crease from underneath. Just like that. Then you can put the model back down. And
we’re going to do the same thing one last time on the right. So we’re simply
going to pick up the right side of the model, we’re going to fold it over along that
crease, then we’re going to reinforce the crease from underneath. Just like this.
Then you can flatten out the model, and now you’ll see that you’ve reinforce
those four creases. And now you can see that I’ve marked these two parallel
creases here. And again we’re going to reinforce these creases, but this time we’re going to make sure
that they are mountain folds. So we’re going to start with this crease on the bottom.
And what you want to do is simply pick up the model, and we’re going to pinch
that crease on the top just to make sure it’s a mountain fold. Then you can put
the model back down, and we’re going to rotate the paper one hundred and eighty
degrees. And we’re going to do the same exact thing. So just reinforce this
crease here by simply picking up the model. Again we want to pinch that crease
from the top, so just pinch it like this to make sure
it’s a mountain fold. And then you can put the model back down. And now you have
reinforced these six creases. This will make it a lot easier when
you’re trying to collapse the rest of the model. And now we’re going to turn
the model over. And once it’s turned over, we’re going to fold the entire model in
half along this existing horizontal crease. So what we’re going to do is simply pull
down the top half of the model along that existing crease. Then you can flatten
it out, and your model should look like this. And now we’re going to reverse fold
along these two creases that I’ve marked here. So we’re going to start with this
right side and we’re simply going to pick up the model and look at it from
the top. I find it easiest to slightly separate
the layers, like this. And then you can see that we’re going to reverse fold
along these two creases that I’ve marked here. And I find the easiest to pinch
these two creases from the top, so just pinch them like this to make
sure they’re both mountain folds. And then what you want to do is push this
bottom corner underneath the model. So just push it in like this. Then you can
bring the left and right sides of the model together, just like this. And if you
lay the model down flat once again, you’ll see that you’ve reverse folded this
corner here. And once you have this, then we’re going to do the same thing on the
left. So again we’re just going to pick up the
model, and we’re going to look at it from the top. Again I find it easiest to
slightly separate the layers. And then what we’re going to do is pinch these
two creases from the top, to make sure they’re both mountain folds. So just
pinch them from the top, like this. And then what we want to do is push this
bottom corner underneath the model, just like we did on the other side. Just push it underneath like that. And
then we’re going to bring the left and right sides of the model together. And then if you put the model down flat
once again, you’ll see that you’ve reverse folded this corner here. And once you’ve
done that on both sides, your model should look like this. Now we’re going to lift up the model, and
we’re going to look at it from the top. Then what we want to do is slightly
separate the layers like this, so that you can see these two colored flaps that
we just reverse folded. Then what we’re going to do from here is collapse along
existing creases just to lock the left and right sides of the model in place. So
we’re going to start with the right side of the model, and what we want to do
first is bring these two layers on the right colored flap together. So simply
pinch the layers together from the top, just like this, just so that you can see
the white side of that flap. Then you’ll notice this existing crease here which
runs up and down the length of that flap. And now we’re going to fold the top
layers of this flap down along this existing crease that I’ve marked here. So
we’re going to do that by simply pulling down the layers on the top of that flap
and folding them down along that existing crease. Just like this. And as you’re doing this, you’ll see that
that flap does not lie flat. So what you want to do is simply push
that flap over to the right as far as it’ll go. So you’re basically pushing the paper
over to this bottom right corner. And once you’ve pushed that flap over to the
right as far as it’ll go, you’ll see that the creases on the flap
will align with the rest of the creases on the model. So once you have something like this,
we’re going to bring both sides of the model together, just like this. Then you
can put the model back down flat and we’re simply going to flatten out the
paper by reinforcing those existing creases. And now you have locked the
layers on the right side of the model in place. So what we’re going to do is simply turn
the model over, and we’re going to do the same exact thing. And now we’re going to
pick up the model and we’re going to look at it from the top. Then again we’re going to slightly
separate the layers, and from here you can see that the layers on the left are
now locked in place. So we’re going to do the same exact thing with this right
colored flap here. So once again I find it easiest to start
by bringing the two layers on this right colored flap together. So we’re simply
going to grab the layers from the top, and we’re going to pinch them together,
just like we did before. Then we’re going to look at the model from the side, just
so that we can see the white side of that flap. And then you’ll notice this
existing crease that I’ve marked here, which runs down the center of that flap. So what we’re going to do is fold the
top of that flap down along that existing crease. So we’re going to do that by
grabbing both of the layers on the top of that flap, and we’re just going to fold them down along
that existing crease. And as you’re doing this, you’ll notice that the bottom of the
flap does not lie flat. So we’re simply going to push the
remaining layers over to the right, as far as they go.
Again you want to push those layers into this bottom right corner as far as
they’ll go, just like this. And once the flap is in place, you’ll see that the two creases I marked
here will align with the creases on the rest of the model. So from here we’re simply going to bring
both sides of the model together once again. Just like this. And then you can
put the model down flat, and we’re simply going to flatten out the model by
reinforcing those existing creases. And once you’ve done that, then you’ve locked the
layers in place on the left and right sides of the model. And now you’ll notice
these two creases that I’ve marked here. Those are two of the valley folds that
we reinforced earlier. And what we’re going to do is pick up the model, and
we’re going to slightly push down along both of those valley folds. Just like
this. So we’re just going to slightly
reinforce both of those creases, and you’ll see that the model is slightly
taking shape. So what we’re going to do is turn the
paper over, and we’re going to do the same thing. And again you’ll notice these two
creases that I’ve marked here. Those are the other two valley folds that we
reinforce before. So once again we’re going to slightly
push down on both of those valley folds, just like this. And then the model should
look like this. And now we’re going to rotate the paper
so that the valley folds are now on the right. And then we’re going to look at
the model from the top. And what we want to do from here is pull apart the left
and right sides of the model, just like this, so that the layers in the center of
the paper are no longer touching. And from here you’ll see that there’s two small
flaps and two large flaps on the top of the model. So what we’re going to do is again push
the left and right sides of the model together, but this time we want to make
sure that these two small flaps are on top of the bigger flaps. So as you’re pushing both sides of the
model together, you want to rearrange the layers so that the two small flaps are
now on top, just like this. And then you can continue to push the left and right
sides of the model together, so that the layers come to a close in the center. And
you’ll also see that the valley folds on the top and bottom of the model will
align. And once you have this, then you can put the model back down. And this is
one completed unit. Now you must fold five more. Once you’ve folded all six units, we’re going to need two to start the assembly.
So we’re going to start with our first unit here, and we’re going to hold it
like this so that the three points are now held upwards. And then we’re going
to take the second unit, and we’re going to hold it behind the first unit. Just
like this. And once you have this, you’ll see that both of the units are aligned.
And now you’ve connected two units. So we’re going to take a third unit, and
we’re going to hold it like this, so that the three points are facing to the right.
Then what you want to do is place the third unit on top of the first unit, just
like this. And then you’ll see that all three units will align. And now you’ll
see that you’ve connected three units. So we’re going to take a fourth unit, and
we’re going to hold it in the opposite direction of the second unit here. So
we’re going to pick up the fourth unit, and we’re going to rotate it so that the
three points are now held away from you. Then what you want to do is slide this
fourth unit in between the first and the third units, just like we’ve been doing. And once you’ve done that, your model
will look like this. You’ll see that all four units will align. And now we’re
going to add the 5th unit the same way. And we’re going to do that by holding it
in the opposite direction of this third unit here, so we’re going to pick up the
5th unit and we’re going to hold this so that the three points are now facing the
left. Then from here you want to hold the 5th unit above the right side of the
model and you’re simply going to slide it down, so that it aligns with the other
four units. Just like this. And now you’ll see that you’ve connected five units. So
in order to add the last unit, we’re going to look at the model from the top.
And in order to add the sixth unit, you’re going to need to slide it under these
two units here. So we’re going to take the sixth unit and we’re going to hold it
like this, so that the three points are facing downward. Then what you want to do is slightly
separate these two units on the top of the model, and then we’re going to slide
the sixth unit in between them, just like this. Then you can push the sixth unit down
from the top, and bring all the units together. And depending on what type of
paper you used, you may need to push the units together a bit just to keep
everything in place. And once all six units are aligned, your model should look
like this. And your origami Burr Puzzle is complete. I hope you enjoyed this video tutorial

  1. I am going to try to make this , I like the way you explain steps so everyone can understand.I subbed! Have a nice day!

  2. A cool tutorial, very detailed, and fun to learn. But I think you should make a tutorial with the same model, but a faster one for people who are more advanced at origami and don't need as detailed instructions. Great tutorial! 😀

  3. Thanks for watching! You can find the paper that I used here: https://amzn.to/2YrkLax
    Tag your photos with #ezorigami to be featured in my next video!

  4. A very clear and detailed tutorial, although you should have some practice in origami when you fold it.
    If you want to use patterned paper you should also have some practice because you can see the folds better when you use paper of one colour.
