Full set of rings with embossed numbers for proper ring sizing. Models are named by US size but a conversion chart has been provided as well for international sizing. An organizer has also been added to the file / print list.
Disclaimer: Ring sizing charts very widely on the actual ring inner diameter, I chose the most common sizing numbers I could find.
The inner diameter has been modeled to the nominal ring size, so you may want to increase the scale by 1% to account for nozzle squish / die swell. However I find my Prusa Mk3S+ prints within about a 50 micron (0.05mm) accuracy, so in that case no need to scale.
FreeCAD models included.
If you're looking for a basic ring that does not have size number embossed on them, I've created a listing for those as well:
Chosen by shared tags first, then category. Each one links to its own marketplace.
