TriCopter Twist Puzzle

Geometry:
TriCopter Twist is a twisted prismatic version of my previous Edge of Insanity puzzle. This one is a bit harder than the other TriCopter 6 puzzles since some pieces now need to be aligned, but mostly because it is difficult to identify when to stop a turn and start another. The puzzle has six axes, one at each 90 degree edge. Because the axis system is based on the triangular dipyramid, every move is a jumbling and shape-shifting move.

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. Use a heat gun or other heat source to get the curved stickers to conform to the curved surfaces.
Screws: Six 12mm M3 pan head screws required, available in hardware stores or on the web.
Springs: Six springs needed, available in web puzzle shops. I get mine from HK Now Store.

Degree of Difficulty:
Assembly: Inside-out core requires dexterity to assemble. Warning: The stickers are very difficult to apply!
Solving: Difficult to solve.

Playability:
TriCopter Twist turns very easily, and the mechanism is very stable.

Have fun!
