I've upgraded my SimpleWallet design and made it thinner. It still can fit up to 6 cards inside.

Printing the slider part was hard and looked bad with supports, so I removed it. Now you can just open it by sliding your finger on the side.

Currently, the wallet does not have a compartment for cash. But I am planning to add it in the next version again.

Tips:
-Adjust the bed temperature so the outside part holds on to the bed properly and the inside part does not warp during printing.
-Putting the parts together is a little bit hard, you need to use some force but try not to break it.

Use brim while printing the outside for surface adhesion.
