Slim 90Degree MK52 heatbed cable cover for Prusa MK3

thingiverse

I had initially uploaded this design to my MyMiniFactory account after discovering tcurdt's inspiring cover which led me to create this cable cover in the first place. So even though this isn't technically a remix, I'm giving credit where credit is due for the inspiration behind the design. This slim 90-degree heatbed cable cover is designed for Prusa MK3 / MK3s printers and was inspired by tcurdt's andled heatbed cover. However, it has been completely redesigned to make it slightly thinner, easier to print, and incorporate proper cable strain relief using two screws that provide even tightening around the cable bundle. The internal design also offers more room for cables to route. I needed a new heatbed cable cover after upgrading to the MK3s extruder because my extruder-mounted boroscope was colliding with the previous cover I had in place. This design provides ample clearance for my NozzleCam to pass mesh bed leveling with shorter Z movements while keeping a clean view of the nozzle. To make this solution as thin as possible, you'll need to (re-) solder the heatbed cables to the headbed instead of using the screw-mounted method, which is quite bulky. Assembly requires three M3 hex nuts to be press-fit into the bottom part and three countersunk M3 screws to connect everything together. I found all these parts in my spares bag for the MK3 kit (the screws seem to be the same as what mounts the heatbed to the Y-frame). The total height of the cable cover, measured from the heatbed, is just 4mm. Measured from the backmost part of the heatbed, it adds 8.15mm to the back of the heatbed, making it a great enclosure-friendly solution.
