I'm looking for basic models of crystal chemical structures. The most basic example would be a cube, it gets harder though as I next need polyhedrons with one of three angles < 90°, then two, etc.

Is there a database of these out there somewhere? Or is the fastest way to make them myself?

You may find that OpenSCAD regular polyhedron library may serve your requirements.

From the linked site: All polyhedra are centered at the origin and have an edge length of 1. From the linked site:

Included polyhedra:

tetrahedron
octahedron
hexahedron
icosahedron
dodecahedron
cubeoctahedron
truncated_tetrahedron
snub_cube
rhombicuboctahedron
truncated_hexahedron
truncated_octahedron
icosidodecahedron
snub_dodecahedron
rhombicosidodecahedron
truncated_cuboctahedron
truncated_icosahedron
truncated_dodecahedron
truncated_icosidodecahedron

OpenSCAD is a reasonably easy "description coding" program at the base level. I suspect that for something such as this, it might not qualify for the easy reference.

My search also linked up a few Thingiverse entries, but they weren't as sophisticated as the above and may be a subset of the library link.

  • $\begingroup$ Agreed. OpenSCAD is the way to go. There are plenty of crystal and polyhedral libraries for it available online. $\endgroup$
