Z-Axis Manual Adjustment Knob (also Creality Ender 2, 3, 3 pro, CR-10, Hictop, Tevo Tornado)

thingiverse

Here is the rewritten text: This completely redesigned pulley is designed to be correctly secured to the Z-axis and to facilitate rotation. This piece works with all Creality Ender 2 / 3 / 3 pro / CR-10 printers and should also work on all printers with a Z-axis of 8mm diameter. You will need an M4 screw and a ball bearing (type Abec 7) to fix it. This two-piece part replaces the Creality CR-10's (Ender 2 and 3 or Tevo tornado, etc...) Z-axis lead screw; It allows you to manually control the hot end up and down (when steppers are disabled), which I have found to be VERY handy at times. You will need a rolling Abec 7 bearing and an M4 screw to fix it. ----------------------------------------------------------------------------------------------- Update 1: Addition of STL pulley that does not require a ball bearing
