I know there are several designs on here already for this type of wallet, but I like reinventing wheels. Besides, I wanted something specific. I wanted something that would hold three or four credit cards, a pistol permit, a driver's license, insurance cards and a credit card knife. I wanted the cash held in place with a clip and I wanted a window for the ID so you didn't have to pull it out to show it.
For my version of the "Thin / Front Pocket Wallet" you will need six (6) m3x8mm socket head screws.
Print the pieces in the orientation in which they are presented. This will produce the best looking parts with the least amount of support material necessary (only required under the holes for the screw heads on bottom.stl). It also ensures proper strength in the clip.stl.
Once all the pieces are printed, bolt the two halves of the case together with the m3 screws. The clip is glued into the slot on top.stl. I prefer to use Weld-On SCIGRIP 16 acrylic cement. This stuff bonds PLA together just like the old model cement used to, before Big Brother decided with was too dangerous and demanded a reformulation. But I digress...
