Tetrahedral racks

thingiverse

Four identical parts assemble seamlessly into a symmetrical sliding mechanism. Constructing this puzzle requires meticulous attention to detail, and achieving perfectly synchronized movement among all the parts proves an even greater challenge. The design excels when printed vertically without any additional support structures. This collaborative effort was a joint project with Saul Schleimer. The design is available for 3D printing at http://shpws.me/MCng.
