My original wallet design used glue to hold it together which worked great but after the elastic band wore out the wallet was basically trash. So I redesigned it to use brass inserts and some M2 screws so you can easily replace the band!
The outside plates can be printed in whatever you like but I definitely recommend printing the inside plates with PETG as it makes getting your cards out easier especially if you use a textured build plate.
Print at least at .15mm layer height. The countersunk holes for the screws are pretty small and the extra layers at that layer height helps it print nicely.
The design will need some M2x5mm countersunk screws, and some M2x3x3.5 brass inserts, and a replacement Ridge wallet style elastic band. Amazon links below!
When you insert the brass inserts with your soldering iron make sure to do it on a hard flat heat resistant surface. If you do it on a soft work mat or solder mat you could potentially push the hot insert too far into the part. I set my solder iron to 220C and they went in nice and smooth!
I printed mine on my Prusa MK3s+ and the hole sizes came out perfect. If you printer isn't tuned very well you might have some issues, mileage may vary.
