Crazy Split 1x2x3

thingiverse

The word 'crazy' at once refers to the circular design on the top and bottom faces, and the crazy amount of splitting happened in such a simple puzzle! No supports required. I used a short M4 screw with a similar head sized nut glued together as a 'metal core' to make it as stable and durable. 2 Lego 4M axles (370526) are also needed, gluing in is optional. It weights 77 grams and the side lenghts are 44x64x64mm. screw lenght: 12 mm head diameter ≤ 8 mm
