Ender 3 Control Knob With Skirt

thingiverse

I modified the design from another model and attached a skirt around the threaded bolt. To ensure compatibility, I reduced the original file size to 98% in Tinkercad, making it possible to print at 100%. The redesigned base now sits securely on the print bed. Additionally, the extra tab provides a convenient grip for spinning the knob when preparing for filament changes during heating cycles.
