This is a large model (over 7" in diameter) of a semi-regular solid with 60 faces, all irregular pentagons, with 92 vertices and 150 edges. It is the dual of the snub dodecahedron (an Archimedean solid - a dodecahedron with its corners cut off), and is therefore called a Catalan solid). It is distinct from its mirror image. It is printable in white, black, and detail plastics.
