Here are 4 Archimedean solids - see thing:19168 for 4 previous ones.
2} truncated icosahedron,
3) rhombic cuboctahedron,
4) snub dodecahedron
The two solids, in the foreground of the image, with their colors reversed, are truncated icosahedra. The truncated icosahedron is related to the 60 atom "buckyball", thing:12675.
Four pairs of stl files are available for download:
icosidodecahedron_less_faces.stl and icosidodecahedron_faces.stl
trunc_icosahedron_less_faces.stl and trunc_icosahedron_faces.stl
rhombic_cuboctahedron_less_faces.stl and rhombic_cuboctahedron_faces.stl
snub_dodecahedron_less_faces.stl and snub_dodecahedron_faces.stl
The openSCAD files that produced them are collected in 2color_archi_scad_02.zip.
Merge the stl files and print on a dualstrusion machine.
