Ender 3 Extruder Stepper Knob
thingiverse
This knob for the hobbed gear and stepper on the Ender 3 simplifies priming of the extruder by eliminating the need to control the stepper through the printer's interface. The part should work with all printers featuring a 5.5mm diameter stepper on the hobbed gear. To install, be cautious as the fit will be snug but will function properly if handled gently to avoid damaging your printer. Print this part flat on the bed without supports and minimize overhang from the chamfer. Share your creations! Feel free to reach out with any concerns or issues you encounter.
