I wanted to print some knobs to attach my GoPro to it's base, but most of the knobs on here assume you're using hex-head bolts. My local Home Depot only had pan-head screws, so I designed this.

There's a threaded portion at the bottom, so you just need to screw the screw/bolt into place. There are three versions attached, for M5x30, M5x40, and M5x50 screws. I've also attached the Fusion 360 file, so if your screws don't have a 9.15 mm diameter head, you can just change “screwHeadDiameter” to match your screw. There's also a “screwLength" parameter you can adjust if you want to make these for M5x35 (or if, as in my case, your cheap Home Depot screws are actually M5x49).
