After upgrading to the EZRstruder on my CR-10, I wasn't really able to take advantage of some of the cable management solutions others had created. Seeing as I wasn't using the front two screws on the extruder, I decided to quickly whip this together. The standard size will hold the CR-10 cables nicely. If you are running the EZABL or other wires, I've created a larger version to hold the cables.
2 x Screw: M3x18
2 x M3 nut
Just drop a dot of superglue on the sides of the M3 nut cutout to hold the nuts in place.
