Meissner polyhedra are solids of constant width that generalize the Meissner tetrahedra. They are three-dimensional analogs of Reuleaux polygons (Bogosel 2023). Their boundaries consist of pieces of spheres and spindle tori (Hynd 2023). Bogosel (2023) constructed Meissner polyhedra up to 14 vertices.
