Conjoined Cubes is a shape variant of Dave's Diamond, an idea that was originally conceived in 2012, but only now has a mechanism finally been developed to make the puzzle playable and affordable. This variant makes it easier to understand the puzzle, which 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 you can have i.materialise dye the model for you at an extra cost.

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: Moderate skill required to assemble.

Solving: Very difficult to solve.


Conjoined Cubes turns very nicely once broken in, 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!
