Prusa Mk2/S LCD Knob - Flared
thingiverse
My finger slips off the standard Prusa Mk2/S LCD knob every time I turn it. So, I took precise measurements of the original LCD knob and created a new one with a subtle flare at the end of its handle. Now my finger stays firmly in place. You might need to use an X-Acto knife to carefully chamfer the edge of the hole to eliminate the "squish factor" that makes the shaft difficult to insert smoothly.
