This is a remix of Fringe's coin holder (https://www.thingiverse.com/thing:2551923).
Their coin box was made to fit the old metal/cardboard coins. I've updated the model to have deeper grooves so it fits the current cardboard coins.
I've also fixed the coin cutout on the front to be joined with the body, as their version is floating just off the body and causes it to fall off.
The cover from Fringe's coin holder will still work. You can find that at the link above.
