Hexcopter 12 Curvy is a 12 axis edge turning hexagonal prism. Each 90 degree edge of the prism has one of the 12 turning axes. Curved cuts were used to allow all parts to maintain contact with the core of the puzzle.
Other Items Needed:
Dye: If you want the puzzle to be black, you can save money by dyeing the pieces yourself with a nylon dye such as RIT or Dylon. Or Shapeways can dye the parts for you at an additional cost.
Stickers: Template available in the instructions forum. If you want professionally cut stickers, I recommend Oliver’s Stickers.
Screws: Twelve 12mm M3 pan head screws required, available in hardware stores or on the web.
Springs: Twelve springs needed, available in web puzzle shops. I get mine from HK Now Store.
Degree of Difficulty:
Assembly: Very easy.
Solving: Easy to solve.
Hexcopter 12 Curvy turns easily, and the mechanism is stable.
