I made an instructional video on how to customize and get the formatting right for the symbol of your choice:

So the STL files for a generic ring are included on this page, but you should look at the instructional video I made for Rose’s Rebel Alliance iris ring on how to print and assemble it:

The only uncommon material needed for this build is M1 x 6mm cheese head screws. I listed my source under in the .pdf (or .xlsx) BOM under “Thing Files”, but hopefully someone can find a better source.
