Here are some polyhedra models. They're a perfect decoration for geometry and maths enthusiasts. They're also good for educational purposes. 

Included in this model:

-Dodecahedron

-Truncated Dodecahedron

-Small Stellated Dodecahedron

-Great Stellated Dodecahedron

-Great Dodecahedron

-Icosahedron

-Icosidodecahedron

-Truncated Icosidodecahedron

-Rhombicosidodecahedron

-Truncated Octahedron
