Prusa i3 Mk2 Ergonomic Control Knob

I needed a superior knob for my Prusa i3 MK2 control panel, but none of the designs available on Thingiverse met my expectations. To create an improved version, I focused on two key advantages over existing models. First, this design features a four-point star shape that comfortably cradles your right thumb during navigation, eliminating the need to look away from the screen (with a recessed center area for selecting the current option). Second, the back side boasts a flexible socket patterned after the original Prusa knob, making installation significantly easier than a simple hole. In the sample shown, I intentionally changed filament near the end to create a contrasting ring within the central button area.
