Simple Folding Key Holder

thingiverse

I was looking for a sleek, minimalist folding key holder to stash in my pocket (key rings and bulky items drive me crazy). This design is roughly the same size as my trusty Swiss Army knife and doesn't have any sharp edges to poke me in the leg. Print it flat without supports. If you want, enable ironing to smooth out the finish. To assemble, use two machine screws, two nuts, and four washers on either side of the keys (add more washers in between if stacking multiple keys). The holes are 4mm wide, and the recesses for the nuts measure 9.5mm across. The recesses for the screw heads are 7mm wide. I shortened two #6 screws using a Dremel to fit my needs.
