Seriously tough puzzles
Wooden puzzles are beautiful to look at but can be large and heavy. Puzzles are meant to be played with and shared. These 3D printed puzzles in tough nylon or solid stainless steel are great to play with and easy to carry around in a pocket. The puzzles range in difficulty from quite easy to fiendishly difficult and, unless stated, are all my own design. Puzzles work best in White, Strong and Flexible material.
If you would prefer coloured puzzles then you have three choices:
- Order in one of Shapeways standard seasonal colours
- Order white ones and dye them yourself
- Order directly from me through my Etsy shop.
Please note that Shapeways only print the pieces. You will need to work out how to fit the puzzle together. YouTube videos are available for many puzzles to help you with this.

My fourth 4x4x4 cube puzzle design is 4cm wide, with four pieces and a unique solution that includes rotation (hence the punny name).
This is a brand new concept for me. Cost-conscious, as ever, I have tried to create a puzzle cube consisting of hollow cubelets. To make the shapes more interesting I have designed my basic Curly Corner Cube in TopMod and then constructed the puzzle pieces from alternating left- and right-handed unit cubes in Blender.
This means it is possible to create a much larger puzzle without it being too expensive.
Another innovation of the design is the flexibility of the cube pieces (when printed in White Strong & Flexible material). The springiness of the Curly Corner Cube shape means that the puzzle pieces should always fit snugly together without being too loose or too tight.
Convolution is a seven piece serially interlocking puzzle designed by Stewart Coffin, probably the greatest ever puzzle designer. Stewart has generously placed his designs in the public domain, so I am delighted to present my own interpretation of this lovely puzzle. I made my first copy out of wood over 25 years ago and it is still one I go back to periodically. One of the moves includes a rotation and every move locks the next piece into the previous one. The pieces of the puzzle are composed of juxtaposed hollow cubelets using a new design. This gives the whole puzzle a lightness and slight flexibility. It also means that the pieces fit snugly together. The whole puzzle is 4 x 4 x 4 cm in size and relatively inexpensive for a printed puzzle of this size.
This complex cube consists of a single piece. Each corner of the cube is connected to its neighbours by a tortuous path that can be traced through the interior of the cube. The whole cube is quite springy when printed in WSF plastic.
