I designed a 3D replacement coin for Caper Europe.

Better don’t loose one.

You have to print both sides seperately and glue them together.

I recommend a 0.2 nozzle and 0.08 layerhight. I extruded the different parts of the coin as a multiple of 0.08.

Filament used:

Bambulab PLA Metal - Iron Gray Metallic

Extrudr PLA NX2 - brown

I think gold or copper would look even better.
