Crank for Z Axis Rod - Ender 3

thingiverse

I built a custom crank with a detachable knob specifically for the Ender 3's Z rod. Its inner diameter is 8mm, making it compatible with other printers that use the same size rod. I designed the knob as a separate entity from the crank, allowing for easier grip while raising the Z axis. The attachment point uses a robust 3x10mm screw to secure the knob firmly in place. This design makes printing much more convenient.
