This puzzle is 2mm smaller than the one I showed a while ago. Evgeniy Grigoriev has gone even smaller with this amazing fully functional 10mm Rubik's Cube. The video shows myself solving it. I did not make this puzzle. To buy DIY versions (not this 10mm Cube) of Evgeniy's puzzles see his Shapeways shop- http://www.shapeways.com/shops/grigor...
