Models of all 32 Crystal Classes (= crystallographic point groups) for teaching or practice, with spoiler-free, randomized file names. Print as pre-oriented. I used known faces of typical minerals (e.g. diamond and calcite) or small molecule compounds (e.g. tartaric acid and AgI) where possible. For a few groups I could not find documented examples and had to freestyle.
There are 33 files, because one example exists in D- and L-configuration (I didn't bother to do that for all chiral symmetries - you can just mirror the models). The pdf is just a printable A4 game board to help with sorting.
Add color changes for extra fun - but beware that it becomes nearly impossible for students to figure out ;-)
Some notes because people have asked:
- There is one example per point group, but for each there is an infinite number of possible shapes.
- I'm not claiming that all these shapes occur in the form of real crystals (some obviously do because I took them from books or fotos).
