Hello, a cable guide that moves with the cable like a crane.

It has a 2020 profile, that has 1 side with a 4mm hole and the other with the "standard" bigger hole.

Insert the 40mm screw into the cable guide, lock it down with a nut.

put the washer between the 2020 profile and the cable guide.

Put the 40mm screw into the side of the smaller hole of the 2020 profile.

Lockdown the 2020 profile with the brackets to your printer, make sure not to turn the screws too tight, that it will damage the print.

with some cable zip ties attach the cable to the cable guide
