Replaces the factory control knob with something much cooler and easier to control.
Print the Falcon standing up with supports on build plate only and a large brim of at least 5 mil. 100% infill - Prusament Silver PLA recommended
Print the control knob base upside down without supports. PLA of any color is fine, it does not seem to show much.
Once both are printed and cleaned up the knob snaps on to the Prusa and the Falcon snaps on to the knob. Then the user rejoices.
