Móc khóa đựng đồng xu kỷ niệm Sobriety

Key chain to hold your Sobriety coins. The coins given out an AA meetings. Holder has a small hole in the back to push the coin out. As it takes a bit of force to put it in. I'd also recommend a small dab of silicon in it before putting your coin in. Which would help "glue" the coin in with out damaging the coin.

Coin measurement: 30mmx2mm 

Original model created in Autodesk Fusion. Included here as well. Do have a rounded fillet on the edges. But is really too small of an object to make any difference. 

Printed in Prusa Galaxy Black.
