A shopping cart coin keychain that combines a 1 Euro and a 2 Euro coin. Also useful for things like lockers, where you need to put the coin in and get it back later.

Use

Simply take off the outer ring if you need a 1 Euro coin. You can the store the ring in the keychain while you're using it. Afterwards just clip it back in.

Printing

Print without supports.

You can color the smiley by using the fill tool in the colouring section (it should pick up the outlines) or just leave it as is.

I recommend printing “by object” as to reduce filament swaps.

The 2-in-1 coin was my idea. The awesome keychain design itself is from puhlbo: https://www.thingiverse.com/thing:2539236
