The Pinwheel Cube is an original puzzle that I made when I started casting. The first one was sold on eBay, and the version pictured is one I made for myself with a special sticker pattern.
This version uploaded on Shapeways is identical to the 2 originals except for some slight mechanism improvements. The originals needed magnets or ball-bearings because the mechanism used to become exposed mid-turn and could be disassembled with a little bit of force. On this improved version the mechanism is anchored deeper so that can't happen.
When you order the puzzle you will receive all the parts un-assembled and will need to buy an Eastsheen Mini 2x2 to use as the core.
Contact me at QuirkyCubes at gmail dot com for the parts and stickers required for assembly, or to receive a fully dyed and assembled copy for an extra $40.
