About this 3D model

Combine this with any credit card-sized wallets to store UAE Dirham coins. This can store four items of each Dirham coin in a wallet that can hold credit cards, like https://www.printables.com/model/766390 or https://www.printables.com/model/246538 . This does not require any supports. I printed with PETG and 20% infill, though this should not really matter given that the part is not supposed to be under particular physical stress. I designed the holes with a diameter each 0.25mm larger than the official size specification for the coins, which seems to be slightly too much to hold the coins tightly but it still works. I might make a future version with slightly tighter holes. If you live in a country with a different currency this is likely not particularly useful for you but you may take the idea and design a similar thing according to the specification of coins used in your country.
