Meissner Tetrahedron - Solids of Constant Width

thingiverse

Meissner Tetrahedron is an object boasting 4 convex faces. Its width remains consistent across any line passing through its center, granting it the remarkable ability to roll like a sphere despite not being one in shape. Three of this shape's edges must be carefully modified to achieve constant width. This modification involves shaving down each edge slightly. Two distinct variations of the Meissner object are available for upload: Type 1 features the three altered edges converging at a single vertex, while Type 2 showcases these edges sharing a common face.
