LunaCrystal Puzzle

LunaCrystal is based on an alternate sweet spot for the pentagonal trapezohedron. This is the second puzzle in the series, and is slightly deeper cut than the previous LunaMinx. Curved cuts are still needed in order to allow the new "crystal" edges to remain in contact with the core of the puzzle in mid-turn. Like its predecessor, LunaCrystal can scramble quite thoroughly, and has a very unusual 180 degree jumbling move!

Other Items Needed:

Dye: If you want the puzzle to be black, you can dye the pieces yourself with a nylon dye such as RIT or Dylon, or you can have i.materialise dye it for you for a small extra charge (this option is definitely worth it!).

Stickers: Please contact me for the sticker template. If you want professionally cut stickers, I recommend Oliver’s Stickers or Chewie's Custom Stickers.

Screws: Ten 12mm M3 pan head screws required, available in hardware stores or on the web.

Springs: Ten springs needed, available in web puzzle shops. I get mine from HK Now Store.

Degree of Difficulty:

Assembly: Easy to assemble.

Solving: Very difficult to solve.


LunaCrystal turns very nicely, and the mechanism is stable.

Have fun!

Welcome! My goal when designing puzzles is to create geometries that are visually striking and have a complexity belied by their apparent simplicity. Many of my puzzles use odd axis systems, and exhibit strange properties such as jumbling and shape-shifting. Enjoy!
