Ender 3 Pro levelling knob / wheel

thingiverse

I required fresh leveling knobs and leveling wheels for my Ender 3 Pro. The original ones didn't meet expectations, particularly when it came to thread quality. I decided to print new ones using high-quality M4 nuts. All four were printed simultaneously on my Ender 3 Pro without requiring any support. Update: An additional wheel/knob was added with a smaller shaft size of 10 mm. Update: A revised version featuring nuts on both sides of the shaft has been uploaded.
