Mod for Creality Ender 5 - Fine adjustment of the Z axis endstop

It is a Z-axis adjustment system in the Creality Ender 5 printer, it is a good concept, but it has the failure that when loosening the captive nut, it is very easy to turn the screw that touches the endstop, losing the adjustment. With this mod, a fine and precise adjustment is achieved, since only one large wheel has to be moved and the possibility of vibrations and misalignments is eliminated when using a self-locking nut.

Material's list:
- 1 screw M3 x 30
- 1 nut M3
- 1 self-locking M3
