3D Printed Catalan Solids - Medium

In mathematics, a Catalan solid, or Archimedean dual, is a dual polyhedron to an Archimedean solid. There are 13 Catalan solids. They are named for the Belgian mathematician, Eugène Catalan, who first described them in 1865. This set includes the following 3D-printed Catalan solids:

Triakis tetrahedron
Rhombic dodecahedron
Triakis octahedron
Tetrakis hexahedron
Deltoidal icositetrahedron
Disdyakis dodecahedron
Pentagonal icositetrahedron
Rhombic triacontahedron
Triakis icosahedron
Pentakis dodecahedron
Deltoidal hexecontahedron
Disdyakis triacontahedron
Pentagonal hexecontahedron
