I made this mounts to work with WiredEarp's cable chain (link: https://www.printables.com/model/166357-ender-3-v2-cable-chain-mount-along-with-all-other- ), so I can install my gantry's cable at the front of my machine as shown in the photos.

You'll need only 1 short M3 screw, I used the same of my BL touch to hold it in place.

Supports are needed on both parts.
