Cable Bracket for Ender3 Z motor

I needed a guide for the hotend wire loom after I converted to direct drive with the loom now routed in front of the Z extrusion. The loom is just barely long enough to reach Z max, but it tugged on the gantry a bit more than I liked. With this part I can take up all the slack from the mainboard w/o relying on the Z motor to hold the tension.
