A college brought this old puzzle to work, 10 plastic rods that you are supposed to fit into an acrylic cube. It was surprisingly fun and challenging so we both did sniff the web for it but wasn't able to come up with anything. Anyone got any clue? it probably dates back to the late 80s-early 90s somewhere.

Anyway, I realized it was a fun programming challenge to reproduce and that it can be done customizable. I gave it a go and here it is, together with the Openscad code to create any new sequence of the solution you want to.

Note that it is a lot harder than it looks, some colleges spent several lunchbreaks with it without solving it.

How I Designed This ===================

Openscad code

I basically reverse engineered the original puzzle. The algorithm adds the last piece, rod, to the puzzle first and then iterates through all the following pieces (reversed to the solution) in any chosen sequence. For each iteration the previous pieces are added as a void material removing all the intersection points.
