Prusa i3 Mk2 Ergonomic Control Knob

thingiverse

I needed a superior knob for my Prusa i3 MK2 control panel, but no existing designs on Thingiverse met my expectations. So, I created this custom version with two key benefits over other options. Firstly, it boasts a four-point star shape that allows your right thumb to navigate comfortably without taking your eyes off the screen - featuring a recessed center area for clicking the current selection. Secondly, the back side sports a flexible socket patterned after the original Prusa knob, making installation a breeze compared to a simple hole on the back. In the example shown, I swapped filament near the end so that I'd have a contrasting ring in the center button area.
