Description
I made this crank handle with knob to fix my father-in-law's old tripod.
CAD file included to adapt for your use.
I used ASA-CF for the "arm" and regular ASA for the knob & knob core. You can see from the cross section views how the knob spins without requiring a loose screw. I was going to add some super-lube but it spin nicely without any so I left it dry for now.
I used ASA incase it ever gets left in a hot car, otherwise PLA is plenty strong.
