Hi Shapeways fans, Pentafold was proposed by Bram Cohen, inspired by the Gear Fold puzzle and several of Bram's earlier gearing ideas. It is a gear train of five seven-teeth gears. As the gear train has an odd number of gears, it is locked and it cannot turn. Moreover, it is locked by a piece in the center. Pentafold can be folded open in five directions. Once folded open, three gears can turn. This enables to scramble the puzzle. The object of the puzzle is to scramble it and then to bring it back into its original state. "God's number" for this puzzle is five, i.e. it can always be solved in five moves. Bram found a generic easy-to-remember solution that requires at most eight moves. Watch the YouTube video.
