I printed this coin with eSUN PETG on painter's tape, because i didn't have golden PLA, but works great, maybe even better with PLA.

(had some problems with adhesion - consider glue or spray)

This coin is a little bigger than standard 50 cent coin. 

Dimensions 35x35x2.5mm. 

The face is incised by 0.5mm.

The print profile consists of 9 coins with coin like edge, but i added STL's without the edge around the coin.
