I just added a small ramp to the container part of the wallet so it would slide up instead of getting stuck when closing.
The ramp is small and should not block the container in any meaningfull way.
I printed it with a 0.4mm nozzle at 0.2mm layer height using PLA.
I used a MK3S+ for the print.
You can get the other parts of the wallet from the original creator(Agustin Arroyo @flowalistik).
