Knob for 1/4-20 nut

prusaprinters

<p>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).</p> <h3>Print instructions</h3><p>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.</p>
