The Design

Since some have asked for other shapes, here is Version 3 of the Impossible Passthrough/ Vortex Thread Illusion with an Octagonal Base

This also fits perfectly with Impossible Pyramid Passthrough,

Greater Clearances give smooth movement straight from the print.

The “male” part of the thread seems to defy physics by passing through the slightly larger “female” Part

This looks amazing both in 2 pieces or together

Dimensions are approximately: 54mm diameter x 107mm

Let me know if you experience any issues.

Printing

Standard settings should work fine to slice.

Once printed let the build plate cool before trying to remove.
