If I wear tighter pants, I have a hard time digging for my keys, and whenever I sit down, they tend to settle to the bottom in an uncomfortable mass. So I designed a simple clip to keep to suspend them so as to keep from bunching up in the bottom of your pocket, as well as providing quick and easy access. A decently sized key ring is recommended for best use.
I printed mine out of ABS, but PETG would work as well, and I used 3 perimeters, at 0.2mm layer height
