Solids of Constant Width (Reuleaux Shapes)

thingiverse

Spheres are not the only solids that have the same width at any incident angle. These shapes have the same width (height) no matter how they are rotated or rolled. Both Reuleaux tetrahedrons and revolved Reuleaux triangles present the same properties. The only difference is that the center of mass of these shapes does not remain at the same height when rolling around which leads to a unique and interesting type of motion. Print Settings Rafts: Yes Supports: Yes Notes: Most settings do not matter because the mathematical properties of the shapes do not depend on infill or extreme precision of layers. Print the models either as they are or 180 degrees upside down, both with proper support and with a slow enough print speed to prevent drooping.
