iPhone 11 (works with XR too) case with a place to hold 1-2 credit cards.
Includes a soft part meant to be printed in TPU and a harder shell meant to be printed in PETG (PLA would probably work fine as well).
I used a few drops of Krazy Glue to make the two parts hold together. To put the phone in the case, start with the bottom then you can push the top of the phone in.
