4 Piece Passthrough Fidget Puzzle - Print in Place

The 4 Piece Passthrough Fidget Puzzle is an interlocking puzzle created by cutting a octahedron with four curved surfaces. These cuts form a set of smoothly interwoven segments that remain connected yet can move and rotate within each other, creating a mesmerizing fidgeting experience.

Important Note:

This model features multiple floating sections that require proper adhesion during printing. For best results, I recommend using a 0.12mm layer height and enabling a wide tree support area and cleaned buildplate. While functional prints can be achieved with 0.16mm or 0.20mm layer heights, these may result in visible meet lines, slight layer shifts, and increased sagging. To enhance print quality, consider reducing print speed or adjusting support settings.

 

Since all four puzzle pieces are symmetrical, you can mix colors between different filament types or combine pieces from multiple prints. The puzzle in the photos was printed using PLA Sunlu Rainbow01 filament, with mixed pieces taken from separate prints of the same material.

 

Perfect as a desk toy, stress reliever, or unique gift, this passthrough puzzle is both a fun fidget and a conversation starter. Print one today and amaze your friends with its impossible motion!
