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
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
