Cube edge- 4.7 cm / 1.85 inch

Technically this is not really my puzzle and I wasn't sure whether to include it.
It was designed by Oskar van Deventer though inspired by my 4Cubes idea. In addition I sponsored it. This meant I paid for and assisted in it's development. That development started shortly after we finished the 4Cubes. Oskar sent me the computer files / images of his 'Cubes on a Disk' idea. I loved it and paid for a set of masters to be printed. From these I made the first prototype. Unfortunately the mechanism design was not suitable and the puzzle easily came apart.
Oskar then tweaked the design and another set of masters were printed. From these I was able to mould and cast the puzzle you see on this page. The core was too complex to mould so I used a 3D printed one. This second prototype turned out perfect.  
I chose 12 colours since it is a 12 sided puzzle. One cube has traditional colouring and the other has the less common colours like purple etc.
You can buy a DIY version of this puzzle from about $200 at Oskar's Shapeways shop. Please be aware that assembly is not easy so you should contact Oskar before buying for full details.
