I took the diamensions of the original three-finned-knob from Prusa and modeled my own knob. I wanted a spot for the thumb to sit in for easy spinning, as that was what I most disliked about the original. I also dinßt want to have to shift my finger from “Spinning position” to “Clicking position”, because it is of course all about efficiency here! With this knob you can click by pressing anywhere on the face.
I printed it in white PLA, mostly because it was already loaded. Just pull of the old one and push on the new one, done.
The knurling on the outside is mostly for decoration.
The author marked this model as their own original creation.
