Symmetry Element Tokens (single & multicolor)

The symmetry element symbols from the table in section 1.4 of the International Tables for Crystallography Vol. A (here's a link to the pdf from the 2016 edition). The tokens are exactly poker chip sized (39 mm x 3.3 mm). I also included blanks without the symbol.

The singlecolor variant relies on bridging. If this doesn't look good enough with your printer, you could cut the whole print horizontally in the slicer and glue the halves together. You could also do manual color changes at 1 mm and 2.3 mm to get multicolor chips from a single color printer.

The multicolor variant comes in 7 styles (no decoration, ring, checkers, radial, bubbles, sawblade, waves - see images). You have to import both the shell and matching inlay part into the same project. I grouped them to make the process easier, but you'll need a printer with at least 20x20 cm build surface to print the full set in one go. If you want more than two colors, the easiest procedure is: Start by loading the inlay part, then use multimaterial painting on the inner part (i.e. the symmetry symbol) in PrusaSlicer (smart fill with smart fill angle set to 90° will color the whole symbol in one click). Then load the shell and assign it to another color, and you have separate colors for symbol, shell and border decoration.

Note: The “complete" files just contain some models twice (61, 62, 41, 31). If you flip these, they represent the screw axes with opposed direction of rotation (i.e. 65, 64, 43 & 32).
