We have been printing out little puzzles to test dimensional accuracy on the 3D printer in the lab, and it reminded me of a cube puzzle I had as a kid, which is now rather difficult to find information on. I’m putting this on the ‘net largely because coming up with search terms to unify all the relevant information was nearly impossible – I had to go root around at my parent’s house to find my set to connect all the dots. It was the source of many ragequits as a child, and it would be a shame to deprive future generations of the same …stimulation.
