Prusa MK3S Heatbed Cable Support - Modified Original

This is a slightly modified version of the MK3s heatbed bottom cover. I added a rear support for the cables with a channel for a zip-tie. This does add an additional 9mm to the length of the part, so tight enclosure/wall spaces should be checked for additional room. It also adds 2mm of height to the overall part, but that does not affect screw length or any clearances. Otherwise it is identical to the original Prusa part.

Run the zip-tie with the closure in the notch to the right, and the tail feeding down. Do not mount the zip-tie closure on top of the cable, as this could potentially snag the extruder cable and cause problems or even damage. Keep it as flush with the top of the part as possible. Please see the pictures for an example.

I included pics with the part removed - I found black parts, with black zip-ties didn't make for the easiest viewing. The channels are also large enough to fit most small, generic zip-ties.

EDIT
V2 has an additional 9mm extension and a second channel for another zip-tie.
