🌀 Nested Spirals Passthrough

The Nested Spirals Passthrough is a four-piece interlocking puzzle where each part follows a twisted spiral path. When assembled, the pieces wrap around each other into a cube.

Each spiral is hollow and uniquely shaped, and the full passthrough illusion only reveals itself when the puzzle is fully assembled. No magnets, no moving parts — just geometry doing its magic.

Important Note:
The pieces contain large floating areas that require good support to print successfully. For best results, use lower layer height and enable tree supports with a wide base.

The pieces are symmetrical and rotational, allowing for color mixing between different filaments or prints. The model shown was printed in PLA Sunlu Rainbow01, with the gradient transitions highlighting the twist and illusion.
