Custom-sized knob for precise fit on Ender 3 Pro extruder pin
Includes measuring tool to test hole sizes before printing final knob
Print upside-down orientation — no supports needed
Adjustable scale (94–102%) accommodates manufacturing variations

This is a 3D-printable extruder knob designed specifically for the Creality Ender 3 Pro. The knob provides a comfortable grip point on your extruder pin, improving control during filament feeding and extrusion adjustments.

The design accounts for size variations across different Ender 3 Pro production batches. A included measuring tool (printable in ~20 minutes) lets you test multiple hole sizes before printing the final knob, ensuring a snug fit on your specific printer's extruder pin.

Print orientation and scaling guidance: Follow the STL orientation to print without support material. Older models (pre-2019) typically print best at 100% or 98% scale, while newer versions work better at 94–96%. Note that some 2021+ Ender 3 Pro models may not have a compatible extruder pin.
