After the extraordinary success of my fast-and-spinny-Prusa-Mini-knob (25 downloads in 1,75 years) I wanted to refit it to the MK4.
This knob allows for one-fingered operation of the LCD-screen. I like this version best because it is much faster than the original knob and you do not have to “switch finger position” for clicking. Every tenth of a second is important here!
Print with whatever material you want, it is not critical.
The author remixed this model.
Refitted to MK4, larger dimple for the finger, slightly higher
