Ender 3 Extruder Adapter with Set Screw
thingiverse
As many users have discovered, adding a knob for the Ender 3 extruder is an excellent upgrade. However, it can become easily stripped if not secured properly. Frustrated with repeatedly printing new knobs, I designed this adapter to attach to the extruder and utilize your existing knob. Simply superglue it to the bottom of your current knob for a seamless integration. The adapter also features a hole for those who prefer using a set screw to prevent stripping. Layer Height: 0.2 mm Infill: 100% (highly recommended when using a set screw) Note: To achieve optimal results, I suggest scaling the print by 102% due to Cura's tendency to produce slightly over-tight prints.
