Knob for 1/4-20 nut

Just a simple knob that matches some commercial knobs I have on hand. Accepts a 1/4-20 nut (11mm OD) that will press fit in (no heat needed).

Designed so that no supports or rafts are necessary. There's no bridging or overhangs to complicate matters. I used 20% infill and it's sufficiently strong; if it's going to be lighter duty you could easily get away with less.
