Print in Place Snake Cube Puzzle

This Puzzle is a 3D printable version of my favorite puzzle as a child, the Snake Cube. This model prints in place with no supports or post-processing necessary.

I print it at .4mm layer height with a .6mm nozzle in slightly under 3 hours.

As usual, this model is made available for commercial use, and I request 10% of profits but do not have any mechanism to enforce this desire.
