That’s it. Title says it all. It is a very plain, very basic, hopefully sized correctly ring base. Add stuff like designs or don’t, and print a plain ring. Modify it, sell it, test it & give me feedback if ya like or don’t whatever floats your boat lol. I myself am planning on using this as a base to add designs to and then electro form the printed result. Whatever you do or don’t do with this file, good luck 👍
