_Do you find it useful what I made? Your can show your appreciation by taking a photo and upload it as an "i made one"! That would be awesome! :)_
"Completely" Solid Dodecahedron
In geometry, a dodecahedron is any polyhedron with twelve flat faces, but usually a regular dodecahedron is meant: a Platonic solid. It is composed of 12 regular pentagonal faces, with three meeting at each vertex, and is represented by the SchlÃÂäfli symbol {5,3}. It has 20 vertices, 30 edges and 160 diagonals. Its dual polyhedron is the icosahedron, with SchlÃÂäfli symbol {3,5}.
A large number of other (irregular) polyhedra also have twelve faces, most notably the topologically identical pyritohedron with Pyritohedral symmetry, and the rhombic dodecahedron with octahedral symmetry. (Wikipedia)
