Coat Hanger Knob

Didn't see one gf liked, so made this. Prints with a plug, I sanded it a little to fit then plugged the top hole. Top hole sized for a #10 washer, if I need to remove it will have to drill a hole int he top plug and remove it. then print a new plug. Hole leaves 7.8mm for screw head and washer.

Don't use circular supports.
