I’ve been thinking about that myself. Which brand direct drive did you go with? Are you using a single Z drive or have you already upgraded to double?
I used the Creality Direct Drive Extruder Upgrade Kit. It works with all of the Ender 3s I think. I have a 3 v2. Its a good thing I saved the unused parts from installing the Ender Touch because I needed the other optional bracket it came with when I installed this new part.
The biggest pain was removing the old harness and installing the new harness through the mesh wire channels. Everything ells was pretty straight forward.
I do not have two z screws.
