Diogo's Crystal is a puzzle based on geometry developed by Diogo Sousa. The shape is similar to my previous Madness Plus puzzle, but has been altered to create equal dihedral angles at the upper and lower sets of vertices. This allows the three side faces (rhombic faces) to have jumbling interactions with the other six faces, creating more opportunity for scrambling. This is also the same geometry that Diogo used to make his previous Hexapod puzzle.

Note: Do not buy the puzzle in MJF! This material is unreliable, and the print might be unsatisfactory. Only buy the puzzle in SLS.

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 an extra charge.

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: Nine12mm M3 pan head screws required, available in hardware stores or on the web.

Springs: Nine 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.


Diogo's Crystal 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!
