Summary

Simple three-piece Venn Puzzle. Print the part (VennPiece) three times, then put it together to create the sphere, which you can store in the box.

This is quite a challenging puzzle to construct. The protos are from a print I created on a Raise 3D E2 with a 0.6 mm nozzle, 0.15 mm layer height for high quality. Once printed, it helps to file/smooth the sharp tips so they do not have any burrs. You must position the corners very precisely for the three pieces to fit together.

Search for "Venn Puzzle" to find the solution and see how it works.

Post-Printing

File the two sharp corners to ensure they are smooth. Not much is needed, but the fit requires sub-mm accuracy.

How I Designed This

I purchased a metal Venn Puzzle from Craighill, then designed my own in Fusion 360 by slicing a sphere using 8 planes that I figured out from looking at the original puzzle. Each plane is offset 0.15 mm to allow for the fit.
