Medallion Coin Holder

This is coin holder designed to hold medallions, commemorative coins, or other similarly sized objects. It is designed to hold a coin that is 4mm thick by 50mm diameter. It can be scaled obviously for other sizes if needed, or remixed for other sizes. The coin is inserted then a metal key ring installed through the holes to hold it in place. This was created in TinkerCad. I recommend slicing this in Cura and using Tree support to help make the inner ring as smooth and complete as possible. Any filament should do, such as PLA, PLA+, PETG, etc.
