My finger keeps slipping off the standard Prusa Mk2/S LCD knob when I twirl it.

So...I took the measurements of the LCD knob that came with the kit and designed one that has a flare at the end of the handle. My finger doesn't slip off now.

You might have to use an X-Acto knife to chamfer the edge of the hole to remove the "squish factor" to help the shaft will fit easily.
