Slim MK52 angled heatbed cable cover

myminifactory

This is a slim 90 degree heatbed cable cover designed specifically for the Prusa MK3 and MK3s printers. I upgraded my extruder to the MK3s unit, but my boroscope kept colliding with the old cable cover, so I needed a new one that would provide ample clearance for mesh bed leveling with shorter Z movements. This design keeps the NozzleCam clean and offers a clear view of the nozzle while in operation. To achieve maximum thinness, you'll need to re-solder the heatbed cables directly onto the heatbed rather than using screw-mounted cables, which can be quite bulky. The assembly process requires three M3 hex nuts to be press-fit into the bottom part, and three countersunk M3 screws to secure everything in place. These parts were easily sourced from my spares bag for the MK3 kit; the screws appear identical to those used to mount the heatbed to the Y-frame. This design is based on Thing 3474411 from Thingiverse but has been completely reworked to be slightly thinner, easier to print, and incorporate proper cable strain relief using two screws for even tightening. The internal routing system provides additional space for cables, making it a versatile solution. The total height of the cable cover measures just 4mm above the heatbed, adding only 8.15mm to the back when measured from the farthest point. This makes it an ideal choice for enclosure-friendly applications.
