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

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?

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.
