Full set of basic / simple rings in all sizes. FreeCAD models included if you wish to make your own additions. Ring size in the file names are in US / Canada sizes, and a conversion chart has been included for international size.
If you're looking for a full ring set specifically for sizing with the size numbers embossed on them, I've created a listing for those as well: https://www.prusaprinters.org/prints/133792-ring-sizing-with-numbers
The author marked this model as their own original creation.
