Product Description
There are five of these, and they are characterized by the fact that each face is a regular polygon, that is, a straight-sided figure with equal sides and equal angles. The 5 Platonic Solids are the Tetrahedron, Hexahedron (Cube), Octahedron, Dodecahedron and Icosahedron. The Pythagoreans knew of the tetrahedron, the cube, and the dodecahedron; the mathematician Theaetetus added the octahedron and the icosahedron. These shapes are called the Platonic solids, after the ancient Greek philosopher Plato; Plato, who greatly respected Theaetetus' work, speculated that these five solids were the shapes of the fundamental components of the physical universe. **Note: Any model that has a 'FIRST TO TRY' icon is in the experimental printing stage. This means that ordering this model will send it into the "FIRST" test for 3D printing for your chosen material. There can be instances where the model must be updated in order to complete the 3D printing process. If this is the case, you will be notified that your order was canceled and must be placed again. This occurs to allow you to re-approve the updated version of the chosen model before being charged for anything.**
