Summary

I designed it in new FreeCad v. 1.0

Puzzle consists of one bottom, one top, 5 inner, 36 outer parts and one spindle.
Outer parts made from 6 different colors.

There are a 0,1-0,2 mm tolerance between parts. I recommend to print a spindle in horizontal orientation - it's more stronger.

You may solve puzzle in several ways - each colors is in its own circle or each colors is in vertical line.

Have a fun!
