Knob

thingiverse

I've designed this knob with no specific size in mind. It would benefit from some careful consideration, though - if needed, that is. Feel free to comment if you'd like me to update it for your purposes. You're probably familiar with these knobs on photography lights and camera equipment, but I've also noticed them on car roof racks. Just let me know what adjustments you need and I'll be happy to make them.
