Ender 3 Z crank knob
thingiverse
There are a lot of Z-knobs, but none really fitted my needs (or I simply didn't find the right one). This one has a real 4 start T8 leadscrew thread, and will fit the Ender 3's Z-rod perfectly (a bit tight of course). The crank is fittes with a M3x10 headcap screw (but other M3's should also work). this goes with my Z-rod stabilizer that you can find here: https://www.thingiverse.com/thing:4752325
