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 myall-time favorite modular models, and it's not very difficult to fold.

Thismodel requires six square sheets of paper.

Each unit is folded from onesquare, and I recommend using six inch squares to fold the units.

Using six inchsquares will result in a model about three and three-quarter inches wide.

I also recommend using thicker paper tofold this model.

Papers such as Tant and Elephant Hide will work well, but if youdecide to use something more common such as copy paper or kami, smaller squareswill work best.

And once you've prepared your paper thenwe're going to start with our first square with the colored side up.

Andwe're going to start by folding in half diagonally, so take this bottom rightcorner 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 paperso that the crease we just made now runs from the top left corner down to thebottom right corner.

And then we're going to fold in half diagonally in theopposite direction.

So once again, take this bottom rightcorner and fold it up to the top left corner.

Align the corners and the edges, and makeyour 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 wejust made is now held vertically.

And from here we're going to make two smallreference creases by folding these two edges in to align with this verticalcrease.

So we're going to start with this bottom right edge here, and we're simplygoing 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.

Justlike this.

And once everything is aligned, then we're not going to crease all theway.

You just want to make a small reference crease on the top of thiscolored edge here, just like that.

And once you made thatsmall reference crease then you can unfold.

And now we're going to do thesame thing on the left.

So we're going to start with this bottomleft edge here, and once again we're going to pick it up and pull it over tothe right towards the center of the model.

Then you want to start at thebottom of the model and work your way up, aligning the colored edge with thatvertical crease.

Just like this.

And once everything is aligned we're not going tocrease all the way.

We just want to make a small reference crease on the top ofthis edge here, just like this.

And once youhave that small crease then you can unfold.

Now we're going to rotate the paper justlike this so that there's now a reference crease on the right and thebottom edges of the paper.

Now we're going to fold up this bottomedge and align this small reference crease with this crease intersectionhere.

So we're going to do that by simply pulling up the bottom edge, just likethis.

And once that small reference crease is aligned with that creaseintersection, 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 topedge and align it with this colored edge here.

So we're going to do that by simplypulling down the top edge, just like this.

And then you want to align the twocolored edges of paper in the center of the model, and then you can crease allthe way across.

Just like that.

And once you folded inboth sides, your model should look like this.

And now we're going to unfold the twocolored flaps that we just folded in.

And now you'll see that you've addedthese two parallel creases here.

And now we're going to make two parallel creasesin the opposite direction.

So before we do this, you still want tomake sure that there's a reference crease on the right and bottom edges ofthe model.

And then we're going to start by folding in this right edge and we'regoing to align this right reference crease with this central creaseintersection here.

So start by pulling the right edge overto the left, just like this.

And again you want to align that smallreference crease with that crease intersection.

And once everything isaligned, then you can make your crease.

And now we're going to fold over thisleft edge and align it with this colored edge here.

So we're going to do that bypulling the left edge over to the right, just like this.

And then you want to alignthe 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 bothsides, your model should look like this.

Now we're going to unfold the two-colorflaps that we just folded in.

And then we're going to rotate the paper, justlike this, so that the two reference creases are now held on the bottom ofthe model.

Now we're going to fold along existing creases.

So we're going to start by folding overthis bottom right edge along this parallel crease that we just made.

So we're going to do that by simplypulling the bottom right edge over to the left, along that existing crease.

Thenyour model should look like this.

And then we're going to fold in this bottomleft edge along this parallel crease that we made before.

So we're going to start by pulling thebottom left edge over to the right, just like this.

But then you'll see that the creasedoesn't go all the way to the bottom.

So what you want to do is introduce a newcrease by simply creasing across all layers, but you also want to make surethat 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 thebottom portion of the model here.

And now we're going to fold up this bottomcorner and align it with this point here where these two colored edges meet.

You willalso see that the small reference creases come together at that same point.

So what we're going to do is simply pickup the bottom of the model and align that bottom corner with the creaseintersection that I mentioned before.

And once everything is aligned, then you cancrease through all layers.

And then your model should look like this.

Andthen we're going to unfold the bottom corner that we just folded up.

And thenwe're going to unfold the two flaps that we folded in before.

And once you'vedone that, you'll be able to see the new creases that you just introduced.

Thenfrom here we're going to rotate the paper so that the new creases are nowheld on top.

And then we're going to do the same thing on the bottom.

So againwe're going to start by folding in along existing creases.

And we're going to start by folding thisbottom right edge in along this parallel crease here.

So we're just going to foldover the bottom right edge, just like we did before, along that existing crease.

And thenwe're going to fold over this bottom left edge along this parallel creasethat we made before.

So once again we're going to pull thebottom left edge over to the right, just like this.

And then you'll see that thecrease doesn't go all the way across, so you'll have to introduce a new creaseon the bottom of the model here.

But once again you want to be careful whileyou're making this crease just so that the layers don't drift out of place.

So once you folded in both sides, thenyour model should look like this.

And again we're going to focus on thebottom of the model here.

And then we're going to fold up this bottom corner andalign it with this point here, where these two colored edges intersect.

So again we're just going to pick upthis bottom corner, and we're going to pull it up and align it with thatintersection.

Just like this.

And once everything is aligned, then you can makeyour crease through all layers.

And then your model should look like this.

And once again we're going to unfold thebottom corner that we just folded up.

And then you can unfold the two coloredflaps that we folded in before.

And once you've introduced those new creases onboth sides, your model should look like this.

And now we're going to focus on thebottom of the model here.

Now we're going to fold up this bottom corner along thissmall horizontal crease that we made before.

So we're going to do that bysimply pulling up the bottom corner just like this, and we're going to fold it up along thatexisting 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 modelwill not lie flat.

So we're simply going to collapse alongexisting creases, just to flatten it out.

So we're going to start with this rightedge and we're simply going to fold it in along this existing crease here.

And Isuggest 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 topush it over to the left towards the center of the model just like this.

And as you're doing this you'll see thatthe paper will collapse along that existing crease.

Then we simply want toflatten it out, just like this, by introducing a new crease here.

Andthen we're going to do the same thing on the left.

So we're going to fold in this left edgehere, along this existing crease that we made before.

Again I suggest you hold the paper downflat, towards the center of the model.

And then what we're going to do is push thisleft edge over to the right towards the center of the model, just like we did onthe other side.

Again you'll see that the paper will collapse along this existingcrease, and then we're just going to flatten out the rest of that flap byintroducing a new crease here.

And once you've done that on both sides, your model should look like this.

Andthen we're going to unfold all of the colored flaps that we just folded in sothat we're back to the original square.

And then we're simply going to rotatethe paper so that those new creases we just made are now held on top.

And thenwe're going to do the same thing.

So we're going to start by folding upthis bottom corner along this small horizontal crease.

So just pull up thebottom corner, like this.

And then we're going to reinforce that small horizontalcrease, just like we did before.

And once again you'll see that the model does notlie flat.

So we're going to start with this rightside here, and we're going to fold in this right edge along this existingcrease here.

So again I suggest that you hold thepaper down flat towards the center of the model.

Just like this.

And then we'regoing to push this right edge up and over to the left so that it collapsesalong this existing crease here.

Then what you want to do is simplyflatten out the rest of that flap by introducing this new crease here.

Andonce you've done that on the right, then we're going to do the same thing on theleft.

So we're going to fold in this left edgealong this existing crease just like we did before.

Once again I suggest you hold the paperdown flat towards the center of the model.

And then we're going to push thisbottom left edge over to the right towards the center of the model, justlike we did before.

Again you'll see it collapses alongthis existing crease.

Then you simply want to flatten out the rest of thatflap, just like this, by introducing that new crease there.

Andonce you've done that on both sides, your model should look like this.

And once again we're simply going tounfold the colored flaps that we just folded in, so that we're back to theoriginal square.

And now you'll see that you've added these new creases here.

Andnow we're going to fold the model in half along this existing horizontalcrease here.

So we're going to do that by simply picking up the model from bothsides.

And then we want to make that crease a mountain fold, so we're simplygoing to pinch the model from the top, just like this.

So that we fold it in halfalong that existing crease.

And then you can put the model back down flat.

And thenyou should have this.

And now we're going to focus on the top left corner of themodel here.

And now we're going to make a new crease that extends between thiscrease intersection here, and this reference crease on the bottom of themodel.

And I find that the easiest way to do this is to fold this left corner overto the right along this existing crease here.

So we're just going to pull theleft corner over to the right, along that existing crease.

And then you should havethis.

And then we want to use this top crease intersection as our pivot.

So youjust want to hold the layers down flat on the top of the model, then we're goingto pull this flap over to the right, just like this.

And once this edge reachesthat small crease intersection on the bottom of the model, that's when you canmake your crease.

So just crease through all layers, just like this.

And then yourmodel should look like this.

And now we're going to fold up thebottom edge of the flap that we just folded over, and we're going to align itwith this left edge here.

So we're just going to pull up this bottom edge, justlike this.

And we're going to start at this bottom point here, and we're going towork our way up aligning both of those edges.

Just likethis.

And once everything is aligned, then you can make your crease.

And now you'llsee that the top of this flap extends past the top of the model.

So what we're going to do is simply liftup the model like this, and we're going to fold that small flap behind.

So justfold it back like this, and then we're going to crease through all layers.

Andonce all the layers on the top are aligned, then you can unfold that smallflap that we just folded back.

And now we're going to fold this flap over tothe left, along this existing crease here.

So we're going to do that by simplypulling the right side of this flap over to the left, just like this.

And once theright edge is aligned with that crease that I mentioned before, then you canmake your crease through all layers.

Just like this.

And once you have this, then we canunfold the small flap that we just folded over.

Then we're going to grab thiscorner on the top of the model and we're going to pull it to the left as far asit will go, just so that we unfold the left side of the model.

And once you havethis, you'll be able to see all the new creases that we just made.

And once youhave this, then we're going to turn the model over and we're going to do thesame exact thing.

So once again, we're going to focus onthe top left corner of the model.

So again we're going to start by makinga small crease here.

But this time you'll notice that there is no small referencecrease.

So what we're going to do is make ourcrease between this crease intersection here and this point here, where thiscrease intersects with this bottom edge.

So again I find it easiest to fold thisleft corner over to the right, along this existing crease.

So we’re just going to foldthe left corner over, just like we did before.

And then we're going to use thistop point as our pivot, so just hold the layers down flat.

And again we're goingto pull this flap over to the right, just like this.

And once this edge reaches thecrease that I mentioned before, then you can make your crease.

Just like this.

Andthen your model should look like this.

And now we're going to fold up thebottom edge of this flap that we just folded over, and we're going to align itwith 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 leftside of the model.

Just like this.

And once everything is aligned, then you canmake your crease.

And once your model looks like this, then you'll see thatsmall point that extends past the top of the model.

And again we're just going to pickthe 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 yourcrease through all layers.

And then all the layers on the top of the modelshould be aligned.

And now we're going to unfold the small flap that we justfolded 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 existingcrease here.

So we're going to do that by simply pulling this flap over to theleft, just like we did before.

And once the edge of the flap is aligned withthis existing crease, then you can make your crease through all layers.

Just likethis.

And once you have this then we're going tounfold the small flap that we just folded over.

And then you want to grab thispoint at the top of the model and we're going to pull it over to the left as faras it'll go so that we unfold the left side of themodel.

And once you've introduced those new creases on both sides, your modelshould look like this.

Now we're going to unfold the model sothat we're back the original square.

So we're just goingto pick up the paper from both sides, and we're going to release that layer frombehind.

And then your model should look like this.

And now we're going to focus on thebottom portion of the model here.

And we're going to fold up the bottom of themodel by making a new crease that extends between this point here, wherethese three creases intersect with this right edge, and this point here, wherethese seven creases intersect.

So we're going to start by lifting upthis bottom edge, and we want to start our crease at this point where thosethree creases intersect.

So you just want to hold down the paperat that point, and then you want to pull the paper up, just like this, until itreaches this point here where those seven creases intersect.

So once this edge is aligned with bothof those references, then you can make your crease all the way across.

And onceyou have this, then we're going to rotate the paper so that the flap we just foldedin is now held on top.

And then we're going to do the same thing on the bottomof the model here.

So once again we're going to fold upthis 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 thispoint here.

So you just want to hold the paper downwhere those three creases intersect, and then we're going to pull up the coloredflap, just like this, until this edge reaches this point here, where thoseseven creases intersect.

So once this edge is aligned with bothof those references, then you can make your crease all the way across.

Just likethis.

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 markingthe creases that we will need for each step.

And we're going to start by reinforcingthese four creases that I've marked here.

And we want to make sure that each ofthose four creases is a valley fold.

So we're going to start with this bottomleft crease here.

And what we're going to do is simply pick up the right side ofthe 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 todo the same thing with this bottom right crease here.

so we're simply going tolift up the right side of the model, and we're going to reinforce that creasefrom underneath, just like that.

And then you can put it back down.

Then we'regoing to rotate the paper, so that the creases we just reinforced are now heldon top.

And then we're going to do the same thing with these bottom two creaseshere.

So once again we're going to start withthis bottom left crease here, and we're simply going to lift up the right sideof the model, and we're going to reinforce that crease from underneath.

Just like that.

Then you can put the model back down.

Andwe're going to do the same thing one last time on the right.

So we're simplygoing to pick up the right side of the model, we're going to fold it over along thatcrease, 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 reinforcethose four creases.

And now you can see that I've marked these two parallelcreases here.

And again we're going to reinforce these creases, but this time we're going to make surethat 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 pinchthat crease on the top just to make sure it's a mountain fold.

Then you can putthe model back down, and we're going to rotate the paper one hundred and eightydegrees.

And we're going to do the same exact thing.

So just reinforce thiscrease here by simply picking up the model.

Again we want to pinch that creasefrom the top, so just pinch it like this to make sureit's a mountain fold.

And then you can put the model back down.

And now you havereinforced these six creases.

This will make it a lot easier whenyou're trying to collapse the rest of the model.

And now we're going to turnthe model over.

And once it's turned over, we're going to fold the entire model inhalf along this existing horizontal crease.

So what we're going to do is simply pulldown the top half of the model along that existing crease.

Then you can flattenit out, and your model should look like this.

And now we're going to reverse foldalong these two creases that I've marked here.

So we're going to start with thisright side and we're simply going to pick up the model and look at it fromthe top.

I find it easiest to slightly separatethe layers, like this.

And then you can see that we're going to reverse foldalong these two creases that I've marked here.

And I find the easiest to pinchthese two creases from the top, so just pinch them like this to makesure they're both mountain folds.

And then what you want to do is push thisbottom corner underneath the model.

So just push it in like this.

Then you canbring the left and right sides of the model together, just like this.

And if youlay the model down flat once again, you'll see that you’ve reverse folded thiscorner here.

And once you have this, then we're going to do the same thing on theleft.

So again we're just going to pick up themodel, and we're going to look at it from the top.

Again I find it easiest toslightly separate the layers.

And then what we're going to do is pinch thesetwo creases from the top, to make sure they're both mountain folds.

So justpinch them from the top, like this.

And then what we want to do is push thisbottom corner underneath the model, just like we did on the other side.

Just push it underneath like that.

Andthen we're going to bring the left and right sides of the model together.

And then if you put the model down flatonce again, you'll see that you’ve reverse folded this corner here.

And once you'vedone that on both sides, your model should look like this.

Now we're going to lift up the model, andwe're going to look at it from the top.

Then what we want to do is slightlyseparate the layers like this, so that you can see these two colored flaps thatwe just reverse folded.

Then what we're going to do from here is collapse alongexisting creases just to lock the left and right sides of the model in place.

Sowe're going to start with the right side of the model, and what we want to dofirst is bring these two layers on the right colored flap together.

So simplypinch the layers together from the top, just like this, just so that you can seethe white side of that flap.

Then you'll notice this existing crease here whichruns up and down the length of that flap.

And now we're going to fold the toplayers of this flap down along this existing crease that I've marked here.

Sowe're going to do that by simply pulling down the layers on the top of that flapand folding them down along that existing crease.

Just like this.

And as you're doing this, you'll see thatthat flap does not lie flat.

So what you want to do is simply pushthat flap over to the right as far as it'll go.

So you're basically pushing the paperover to this bottom right corner.

And once you’ve pushed that flap over to theright as far as it'll go, you'll see that the creases on the flapwill 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 youcan put the model back down flat and we're simply going to flatten out thepaper by reinforcing those existing creases.

And now you have locked thelayers on the right side of the model in place.

So what we're going to do is simply turnthe model over, and we're going to do the same exact thing.

And now we're going topick up the model and we're going to look at it from the top.

Then again we're going to slightlyseparate the layers, and from here you can see that the layers on the left arenow locked in place.

So we're going to do the same exact thing with this rightcolored flap here.

So once again I find it easiest to startby bringing the two layers on this right colored flap together.

So we're simplygoing 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, justso that we can see the white side of that flap.

And then you'll notice thisexisting crease that I've marked here, which runs down the center of that flap.

So what we're going to do is fold thetop of that flap down along that existing crease.

So we're going to do that bygrabbing both of the layers on the top of that flap, and we're just going to fold them down alongthat existing crease.

And as you're doing this, you'll notice that the bottom of theflap does not lie flat.

So we're simply going to push theremaining layers over to the right, as far as they go.

Again you want to push those layers into this bottom right corner as far asthey'll go, just like this.

And once the flap is in place, you'll see that the two creases I markedhere will align with the creases on the rest of the model.

So from here we're simply going to bringboth sides of the model together once again.

Just like this.

And then you canput the model down flat, and we're simply going to flatten out the model byreinforcing those existing creases.

And once you've done that, then you’ve locked thelayers in place on the left and right sides of the model.

And now you'll noticethese two creases that I've marked here.

Those are two of the valley folds thatwe reinforced earlier.

And what we're going to do is pick up the model, andwe're going to slightly push down along both of those valley folds.

Just likethis.

So we're just going to slightlyreinforce both of those creases, and you'll see that the model is slightlytaking shape.

So what we're going to do is turn thepaper over, and we're going to do the same thing.

And again you'll notice these twocreases that I've marked here.

Those are the other two valley folds that wereinforce before.

So once again we're going to slightlypush down on both of those valley folds, just like this.

And then the model shouldlook like this.

And now we're going to rotate the paperso that the valley folds are now on the right.

And then we're going to look atthe model from the top.

And what we want to do from here is pull apart the leftand right sides of the model, just like this, so that the layers in the center ofthe paper are no longer touching.

And from here you'll see that there's two smallflaps and two large flaps on the top of the model.

So what we're going to do is again pushthe left and right sides of the model together, but this time we want to makesure that these two small flaps are on top of the bigger flaps.

So as you're pushing both sides of themodel together, you want to rearrange the layers so that the two small flaps arenow on top, just like this.

And then you can continue to push the left and rightsides of the model together, so that the layers come to a close in the center.

Andyou’ll also see that the valley folds on the top and bottom of the model willalign.

And once you have this, then you can put the model back down.

And this isone 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 itlike this so that the three points are now held upwards.

And then we're goingto take the second unit, and we're going to hold it behind the first unit.

Justlike 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, andwe'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, justlike this.

And then you'll see that all three units will align.

And now you'llsee that you've connected three units.

So we're going to take a fourth unit, andwe're going to hold it in the opposite direction of the second unit here.

Sowe're going to pick up the fourth unit, and we're going to rotate it so that thethree points are now held away from you.

Then what you want to do is slide thisfourth unit in between the first and the third units, just like we've been doing.

And once you've done that, your modelwill look like this.

You'll see that all four units will align.

And now we'regoing to add the 5th unit the same way.

And we're going to do that by holding itin the opposite direction of this third unit here, so we're going to pick up the5th unit and we're going to hold this so that the three points are now facing theleft.

Then from here you want to hold the 5th unit above the right side of themodel and you're simply going to slide it down, so that it aligns with the otherfour units.

Just like this.

And now you'll see that you've connected five units.

Soin 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 thesetwo units here.

So we're going to take the sixth unit and we're going to hold itlike this, so that the three points are facing downward.

Then what you want to do is slightlyseparate these two units on the top of the model, and then we're going to slidethe sixth unit in between them, just like this.

Then you can push the sixth unit downfrom the top, and bring all the units together.

And depending on what type ofpaper you used, you may need to push the units together a bit just to keepeverything in place.

And once all six units are aligned, your model should looklike this.
