Depending on how dialed in your printer is, you have the choice of sizes for wallet.
Low, medium and high tolerance should give enough options for you to find one that fits just right.
A simple wallet which holds:
Contactless credit card (In the sliding compartment)
This wallet does all 4.
The unique feature is that the credit card acts as a door to the inside, meaning the wallet is simple to print.
This wallet can be printed in place.
The only downside is that change rattles if you shake it!
Prima Filament (Amazon) PLA
This has been designed to work with my printer which has poor tolerance.
This means that if you print this and the cards are too loose use one of the tighter files.
