Dave's Diamond is an idea that was originally conceived in 2012, but only now has a mechanism finally been developed to make the puzzle playable and affordable. The geometry consists of two overlapping but rotationally offset 2x2x2 cubes. Therefore it is a deep cut puzzle with 12 axes of rotation. However, only six of the axes can be accessed at any time. This is due both to the nature of the geometry, and to the mechanism used to make the geometry possible. Once you are using one set of axes, the puzzle must be returned to its original shape (but not color pattern), in order to switch to using the other set of axes.


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 order it in black. i.materialise does an amazing dye job for a very reasonable price.

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: Five 12mm M3 pan head screws, and three 6mm M2 flat head screws required, available in hardware stores or on the web.

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


Degree of Difficulty:

Assembly: Skilled assembly required. This puzzle requires extensive breaking in due to the nature of the switching mechanism. The switch can be extremely difficult to throw at first, but with lubrication and breaking in it will work smoothly.

Solving: Very difficult to solve.



Dave's Diamond turns very nicely (once broken in properly!), and the mechanism is very 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!
