Cuboctahedron 15 Compound, Wireframe

This is a wireframe model of a compound of 15 cuboctahedra with icosahedral edge symmetry,  made by joining a cubeoctahedron whose 4-fold symmetry axis is aligned with the edge center of an icosahedron (or dodecahedron) to a similar one aligned with every other edge. Since the top and bottom edges are parallel, this results in a compound of 15 cuboctahedra rather than 30. The wires in this model are 1mm in diameter.
