In this collection, we showcase 3D-printed polyhedral nets constructed from polypropylene. Leveraging the unique property of this material, the designs incorporate living hinges that soften when placed in hot water. By incorporating neodymium magnets into the design, this effect initiates a spontaneous folding sequence, allowing the nets to naturally form their designated polyhedral configurations.

Description

This resource features 3D-printed nets of three distinct polyhedra: the cube, icosahedron, and dodecahedron. Two variations of the dodecahedron are presented. One unique version exhibits self-intersecting behavior during its folding process, which prevents a successful complete transformation.
