Picture of Modified Rubik's Cube
In this tutorial I'm going to show you how to make a Rubik's Cube, which changes the shape when you scramble it.

The cuboid is easy to make, because you don't have to extend any pieces.

Check out step 5 to see, how to solve it. Basically it solves like the 3x3x3, so if you know how to solve that one, you should have no problems. A big advantage compared e.g. to the Fisher Cube is, that there is no parity.
Also you can easily shove it into your pocket because it is a lot thinner than the original cube.

Step 1: What you need

Picture of What you need
This is what you need:

  • A black Rubik's Cube (Best is a DIY Cube, because you can easily assemble and disassemble it. Also it comes with a set of stickers, which you can later use). You can of course use an assembled cube, but you will have to get rid of the stickers, before you start.
  • self-hardening synthetic clay (I used “Apoxie® Sculpt”)
  • Tiles or stickers (e.g. from cubesmith.com). Just get the regular 3x3x3 sized ones. Tiles are better, because they can compensate small irregularities.
  • a Dremel (Felt Polishing Wheel, SpeedClic Plastic Cutting Wheel)  if you don't have a Dremel, just use a regular saw
  • sandpaper (400, 800, 1000)
  • a black permanent marker
  • a box cutter

That isn't a cuboid, it's a shape mod of a 3x3. It may look like a cuboid with only a 2x3 grid of stickers, but you have to include the corner to the left of the blue, orange, green, or orange face. if it moves like a 3x3 but doesn't shape-shift (like a REAL cuboid, e.g. 2x2x4), or has a sum of the grid X + grid Y + grid Z not evenly divisible by at least one of the grids (if the sum of three grids/grid x, the sum of three grids/grid y, and the sum of three grids/grid z equal each other, you have a cubic puzzle, and you can now use that for calculating the volume using two numbers and you can calculate the third. You're welcome.

If you know how to solve a normal 3x3, is it fairly easy/same solving method to solve this one?

Absolutely. It is solved the same way

Wow, I will have to try this.

 Is that same cube in other games or is it the same one in the same game I play!

I know that cube is in the game Adrenaline!!!
BrittLiv (author)  HeyJD5 years ago

Do you mean the companion cube? It is part of the game portal.

What is a companion cube? I've heard of it a lot but I don't know what it is. :(
HeyJD scistone4 years ago
A companion cube is a cube you find on a level of portal. You have to throw it out straight after the level.So many people like the cube that it became a meme.
scistone HeyJD4 years ago
OK, I HAVE NO IDEA WHAT YOU ARE TALKING ABOUT. ALL I SEE IS "a companion cube is a cube you find on BLAH BLAH BLAH. You have to BLAH BLAH BLAH. So many people like the cube that it BLAH BLAH. Can you please tell me what game this is and what is a portal and what is a meme and how do you throw it and what kind of level are you talking about!?!? Thanks :)
Are you serious?
The Companion Cube is a "character" you meet in the game Portal. Long story short you're a test subject, testing the Aperture Science Portal Gun, that makes portals, by solving some simple puzzles. To help solve your puzzles you're given a companion cube for one level, you're supposed to get attached to said companion cube because (SPOILER: kinda) you're later supposed to destroy it. It's a meme (Just google it) and is ridiculously popular. It's also supposed to be your one and only friend
Ohhhhhhh Yeeeeaaaa. I have heard of people talking about portal. Thanks
HeyJD BrittLiv5 years ago
 Ah, yes. I remember that cube in portal... but that same cube is Adrenaline too.

"oriented" not orientated
BrittLiv (author)  dzurn5 years ago
thanks a lot I corrected it.
"Orientated" is fine too...

Love your instructables by the way
No kidding, they are AMAZING!
BrittLiv (author)  rocketsurgery5 years ago
Thanks a lot, it's not that easy to write an Instructable in a foreign language, so I really appreciate it if somebody corrects me (or corrects the one that corrected me ,-))
CrazySheep5 years ago
The cube is a lie! It's not possible to make something that amazing! :0
Cube. Cake. Same thing, really.
the cake is NOT a lie!
Well, it is and isn't :P The player gets to the cake, but the actual character never does...
exactly c:
i will miss mine since i killed it in Portal :´(
Same! D:
Bob13254 years ago
you killed a DIY for this!!!!
BrittLiv (author)  Bob13254 years ago
You can use a normal cube, but it's going to be harder to make and the result will not be as good.
why is that?
Sorunome4 years ago
cool!! but you can buy them...
Where? I've seen a whole lot of types of Rubik's Cubes for sale but never one like this. I would like to buy one pre-assembled so a link would be great. And even if you can actually buy one this is an awesome Instructable! Apparently enough people agree that it is one of the BEST Instructables for 2010 Great Job BrittLiv!
BrittLiv (author)  Bad Maxx4 years ago
Hi, thanks a lot, just search for windmill cube. Like the name says it's a cube, I prefer the cuboid though, because it is thinner and you can easily shove it into your pocket.
the one of cubikon has the size of a normal rubik's cube...
BrittLiv (author)  Sorunome4 years ago
Hi, I know, I've got it (I'm German, too), I still prefer the thinner one though.
why that?
BrittLiv (author)  Sorunome4 years ago
Like I said you can easily take it with you.
Thanks for the info guys!
np! ;)
i see
srry, german website: http://www.cubikon.de/alle-produkte/fisher-cube-crazy-3x3-weiss/a-9150/ (i'm german)
mabe you find it somewhere else. I got that one for Christmas!! :D
When that cube's all scrambled to infinity, it kinda looks like/reminds me of transformers haha!
By the way (it just popped into my head just now), would this be possible with a 4x4 cube? That would be so hard...
BrittLiv (author)  nutsandbolts_644 years ago
Hi, yes you can, but you will have to extend the pieces in order not to damage the mechanism and you will have to be careful, because there are different types of 4x4x4's.

Ill do this but where do you get the DIY rubiks cube??
BrittLiv (author)  AwesomeSwordGuy4 years ago
Hi, I always get mine on ebay. Just search for "diy 3x3x3" most of them come from Hong Kong, which means, that it will take a while for them to arrive (but they are a lot cheaper). If you want to order more than one cube and different types, have a look here
i found them but they're all in white or come without stickers
BrittLiv (author)  AwesomeSwordGuy4 years ago
Where have you been searching? I found quite a few on ebay, e.g. here
Yeah, but......these are good DIY's
some people simply like quantity over quality man I much prefer having very good DIY's but it's all choice
goto speedcubeshop.com or cubingstore.webs.com they both sell a variety of DIY's and they are quite cheap with good shipping
glugnar4 years ago
so this is basically a 3x3x2? it kinda looks that way in the picture on the sides
BrittLiv (author)  glugnar4 years ago
Hi, that's probably why so many people have trouble solving it, even though it can be solved in the same way as a 3x3x3. It is not a 2x3x3.
ya i saw that it was not a 3x3x2 but i didnt know how else to solve it lol
By the way great instructable 5/5
hlfwy.thr5 years ago
Wow. I've never seen anything like this before. Looks really awesome. I might just have to do this... once i get my hands on a dremel
BrittLiv (author)  hlfwy.thr5 years ago

You don't really need one, a belt sander or even a rasp will also work.

What about an orbital sander?
BrittLiv (author)  Saturn V4 years ago
Sure, it will work as well
crazyg BrittLiv5 years ago
yep i thought belt sander would be way to go
Or if you have a ton of time. A flat file will work. or maybe even a knife sharpening stone. But it will take a LONG time

Did you cut your finger in the process of making this cube?
BrittLiv (author)  macmundi4 years ago
I sometimes wear adhesive bandage to prevent cutting in my finger, but in this case I had salad for lunch and accidentally cut myself in the preparation. I still remember it, because it was so stupid...
on step 6 the cube looks like the ones found in portal (the game)
CaseBoy5 years ago
 hey I got a cool idea in school, tell me what you think.....instead of cutting it in the shape of a different square why not a circle? 
BrittLiv (author)  CaseBoy5 years ago
Hi, it's called Cylinder Cube, Tony Fisher made one in 2001:

I would encourage you to make it, because I think it looks pretty cool.

If you want to make an entire ball watch this video:

 just one question....would the way to solve it stay the same
BrittLiv (author)  CaseBoy5 years ago
Yes it does, you are not changing the mechanism. Have fun building it...
thanks...but 1 more question if you laid the stickers out differently wouldn't that cause an error in that way to solve it...?
BrittLiv (author)  CaseBoy5 years ago
The cube in the left picture has one extra layer, if you are going to make it out of a 3x3x3 it has only 5 colours. It is actually a lot easier to solve.
thanks for the quick respond. Already made one going to make another!!
BrittLiv (author)  CaseBoy5 years ago
cool, are you making them for yourself? I would love to see a picture!
yes i did make one..but it could of been better.
Photo on 2010-06-18 at 08.49.jpg
BrittLiv (author)  CaseBoy5 years ago
thanks, I think it looks good, just needs some sanding
currently starting a another one....a little more complex. I will post pics as soon as i has done.
CaseBoy CaseBoy5 years ago
so basically it will look like it in the first 2:00 minuets of this vid... http://www.youtube.com/watch?v=_Fvd-1w5LrI&feature=related anther question foe you thought. how would the stickers go no an d where would each color go?
CaseBoy CaseBoy5 years ago
so basically it will look like it in this vid... http://www.youtube.com/watch?v=_Fvd-1w5LrI&feature=related anther question for you thought. how would the stickers go no an d where would each color go?
BrittLiv (author)  CaseBoy5 years ago
Hi, nice idea, I've watched the video before, but never thought of building a 3x3x3 that way. Like he does it I would use more colours and use one colour per side. If you take more colours it will look a lot harder to solve even though it's still solved the same way.
minime123585 years ago
so when solving it, the centers can be oriented differently. Is this something you should just solve when solving the top layer? or is there an algorithm to do at the end (such as the swap centers pattern or checkerboard). I dont usually solve it the layer method, so an end algorithm is better. P.S. you should post a pic of checkerboard cuboid (even as your main picture) it looks like a saw blade.
BrittLiv (author)  minime123585 years ago
I'm glad, that you were able to finish it. I'm sorry, I don't know an algorithm that you can use at the end, to solve the middle pieces... Maybe you can figure one out. You are right, it looks pretty cool as a checkerboard.
minime123585 years ago
Im in the process of making my cuboid. I accidentally broke two of the pieces and its going pretty insane >.< I think the main problem is that im being to cheap to buy the right clay and using hot glue instead :D Btw I used a pull saw to cut through it and it cut it fast and nicely. (the broken piece wasnt because of the saw, it was because my lines werent very straight. I'll try to post pics when im done
BrittLiv (author)  minime123585 years ago
Hi, yeah it happened to me too, it depends a lot on the quality of the cube that you use.
Yah this one was one of the older rubiks brands. It is actually working pretty well, I just need to remake one of the pieces cause I cut off of the line accidentally. Im thinking of making a mold somehow of an identical piece
vigilantice5 years ago
For cutting it, could I just draw the lies and run it through a vertical band saw?
BrittLiv (author)  vigilantice5 years ago
I've never tried it, but as long as it's strong enough and not to rough it should work. Please tell me how it went.
minime123585 years ago
So, from what i am getting, the cuboid is the exact same solve as the regular cube ( because the pieces are the same.) Is it the same for the truncated cube?
BrittLiv (author)  minime123585 years ago

Basically yes, except for one tiny difference. It is possible, that the last corner is oriented in the wrong way, even though everything else is solved. But I am sure you can figure out how to solve this...

 Just so you know, this mod you explain in this tutorial is called a Windmill Cube.
BTW, the other mod you have is called HALF Truncated Cube (Truncated Cube is different since ALL corners are cut.
BrittLiv (author)  Nicolas M5 years ago

Hi, thanks, yes of course you are right, it's a HALF truncated cube. The Windmill Cube is as the the name suggest a cube. In order to make it you will have to extend the piece.

 Oh so since you didn't make extensions you didn't call it Windmill Cube?
Or was it because of Copyright(c)?
BrittLiv (author)  Nicolas M5 years ago

I don't think it is a copyright infringement, if you show people how to make something, but I might be wrong... I made the cuboid first and then searched the internet, if there is something similar to it. I found the Windmill cube, but I thought writing “Make a windmill cuboid” or something similar sounded stupid... That's why I simply left it out.

 COOL. But I still have a question (not about this specifically), do you know any other cool mod you could share with me?, cause if you have like a link or someting it would be nice to know, you know, you should in fact visit cubemania.co.kr
Anway, looking forward to get an answer.
BrittLiv (author)  Nicolas M5 years ago

Did you take a look at the last step? www.speedcubing.com/ton/ is my opinion a very good site. Thanks for the link, I've actually joined quite a while ago and couldn't find it anymore... I've added it to my list.

You probably already know http://twistypuzzles.com/forum/viewforum.php?f=9 If not take a look at it.

 Thanx, I actually knew the first link from a while ago, the second one though, was really helpful and new for me.
Did you know the time traveler's website?, http://www.chrono.org/puzzles.html
is really good as well as Jaap's puzzle page, http://www.jaapsch.net/puzzles/
or his links page, http://www.jaapsch.net/puzzles/puzzlink.htm
as well as the puzzle shop/museum, http://www.puzzle-shop.de/
A gain thanks.
BrittLiv (author)  Nicolas M5 years ago
I only knew the last link, so thanks a lot! Have you ever built your own puzzle? It seems as if you've spent a lot of time getting to know more about the Rubiks Cube.
 Well I do know how to build many many rubik's cube-like puzzles variations, nonetheless I still have only done some really simple mods as the siamese cube or the 2x2x1 (which mainly consist of gluing pieces), and I have never gone into a more complex thing, mainly because I still don't have the necessary tools (i.e a Dremel) but I've been thinking about buying a good Dremel kit with multiple bits and then I'll get working on some serious moding. Also I haven't done that kind of mods because I'm 13 (a couple months away from being 14) and so my parents won't really let me use "dangerous" tools. I've mannaged to convince them about maybe buying me the kit as I already said and maybe do the cutting under supervition of my dad. So that's about it, by the way, you made me curious, what other mods have YOU made?
BrittLiv (author)  Nicolas M5 years ago
My aunt gave me my first Dremel (she works for Bosch), I can't quite remember how old I was, but I was for sure younger than 10 and up until now I only hurt myself once (half a year ago with 22, while making my Lego figure flash drive and even that wasn't to bad). Believe me a knife or a saw is far more dangerous (considering the number of scars in my index finger). Still you should concentrate and wear safety glasses, to minimize the risk (and if you are working with the cube a breathing protection, believe me you don't want to cough black dust, I've been there).
I started making puzzles about a year ago, my first one was a Fisher Cube.
Then I built a Siamese Cube, it is fully functional, because I didn't just glue the pieces.
Other than those shown here I made a Domino Cube, a 1x1x2, a 3x3x4 and a few mini cubes (love them ;-)). Well and of course my flash drive (even though it probably doesn't count...). 
 Yes is true non-electrical tools are way more dangerous, but when I said the thing about "dangerous tools" I meant Dremels, cutters, knifes, saws etc. so I kindda have only used a saw (with gloves and assistance) and a drill.
BTW, how's that of the fully functional siamese, how do you make it?

 I've finally started making mine, but the only thing I can think is "How the heck do I cut through this cube with such a small dremel cutting wheel?"
What is the trick to cutting all the way through the cube? Do one piece at a time?

BrittLiv (author)  Kaiven5 years ago

Hi, I cut one layer a time (If you have something bigger to cut the pieces you should use it). Sadly I didn't take any good pictures. Maybe these two will help:

Kaiven BrittLiv5 years ago
 I figured so. I took apart the whole cube and marked each piece separately. Then, I cut each one with my dremel. Took four hours....
But it is soo cool! Even without the holes filled in yet, I can solve it because the sides aren't the same shape. It was fun showing it to people at school too.
I still need to get some clay or something... I plan on painting the sides because that's how my cube originally looked.
BrittLiv (author)  Kaiven5 years ago

Four hours o.0 wow... I'm impressed by your patience ! I would love to see some pictures when it's finished...

Kaiven BrittLiv5 years ago
 Haha, yes, I can be patient when I am focused on one of my projects. Yet I can't focus at school.... hmmmm....

Definitely going to post pictures. I used crayola air-dry clay, so It won't be done for another day or so.
Duke Luke5 years ago
So do you just leave the cube as it is and attack it with the Dremel, cutting straight down?
Or do you draw these lines on the bottom of the cube as well and then take it apart and cut?
BrittLiv (author)  Duke Luke5 years ago

I didn't take it apart, if you are using the dremel speed clic wheel you won't be able to cut straight down, that is why I cut layer per layer. But like I said before, if you have anything bigger to cut the pieces you should use it.

LEAH1565 years ago
dude that is cool i made one and everyone at my school asked how to do it
BrittLiv (author)  LEAH1565 years ago

Thanks, I would love to see some picture of your cuboid.

Zorink5 years ago
Great project!

What type of cube would you suggest for this? Rubiks.com has a few variations of the DIY official cube and there are other variations at Cube4You.com.
BrittLiv (author)  Zorink5 years ago

Hi, you don't need to get an expensive original one. Mine is a type C. Here is a very good thread:


knex lord5 years ago
i realy loved your post 5 out of 5 stars i have solved alot of cubes and i was wondering where did you get the truncated cube because i would realy like to solve it if you could drop me a line it would be grate thanks
BrittLiv (author)  knex lord5 years ago

Hi, I've made it myself. I don't think you can buy it anywhere, but it is very easy to make... you don't even have to cut the the stickers (http://cubesmith.com/half-truncated.htm) (at least for the normal sized one)

zascecs5 years ago
Wow, this is so cool; the only problem is that if I have trouble solving the regular kind of cube, I don't know about this...

 Nice!  I'll try to make one... how fast can you solve a standard 3x3?
My average is about 25 seconds...
BrittLiv (author)  MotaBoi5 years ago

Thanks a lot, I'm very slow because I still solve it with the beginners method. I started to study the Fridrich Method, but got bored after a while. I prefer to modify them.

laxap5 years ago
Genius! 5*
When solved looks like an impossible 2x2x3 cube...

Question: the fact that corner pieces look like edge pieces (w/ only two colors), and almost vice-versa... is it confusing? does it make it harder to solve? or does one get used to?
BrittLiv (author)  laxap5 years ago

Yes, it is a bit confusing. It is really fun to see people struggling who are usually able to solve it very fast ;-) 

Veovis5 years ago
 Awesome! If i have some free time I'll try to make one.  I like the companion cube.  Is that just a 2x2 with epoxy or clay on top?
BrittLiv (author)  Veovis5 years ago

Thanks a lot! Yes it is a 2x2. I used cardboard and Apoxie Sculpt.
