Card coin holder (for e.g. Lockcard Wallet)

I didn't like other solutions where I could combine banknotes and coins. It is noisy and annoying to get the coins out of the tray.

So I found an already nice solution from mirabatek but I had difficulties pulling it out of the wallet. So I've created my own with a nice round fillet at the back and flat front for a clean and nice finish. I recommend using a good sliding material like PLA-Metal, which I've used to easily pull out the card without pulling out other cards.

I was inspired by mirabatek but did not use his STL and created my version.

Update:

I've made 2nd version with a second hole to pull the card from the bottom as well.
