Simple Folding Key Holder

myminifactory

I needed a lightweight, portable folding key holder that would fit neatly in my pocket without any cumbersome accessories or protrusions. I'm pleased to report that this design is roughly the same size as my trusty Swiss Army knife and features a smooth profile with no pointed edges to worry about. To print it flat, you won't need any supports. If desired, ironing can also be enabled for extra crispness. Assembly is straightforward, requiring just two machine screws, two nuts, and four washers placed on either side of the keys (additional washers can be added between keys if necessary). The holes are 4mm wide, while the recesses for the nuts measure 9.5mm in diameter. The recesses for the screw heads are 7mm wide. To accommodate my two keys, I shortened two #6 screws using a Dremel to prevent them from getting in the way.
