What it does

A folding cube that opens, closes, and hinges through a satisfying loop. Print-in-place. Pulls out of the printer ready to fidget.
The trick is the hinge profile. The "fat hinge" version uses thicker pivot pins than the original Kobayashi. They survive constant handling without the snap that kills thin-hinge versions in a week. Flat layout means no hinge fusion issues during print.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
