coin tray for I-Clip wallet

This is a small and thin tray in the shape of a credit card.
It is designed for the I-Clip wallet and for Euro coins, but it may fit other types of wallets and currencies as well.
The overall height is just 3 mm.
The inner dimensions are about 81 x 50 x 2,5 mm, so the bottom plane is just 0,5 mm.

I recommend at least PETG for a reliable and sturdy print.
I have been using it for half a year now and it still works and is not worn out or anything.

print settings:

layer height: 0,1 mm
material: Prusament PETG Jet Black
