20 mm 90 deg heat bed cable cover for Prusa Mk3

thingiverse

As a lot of other people, I'm going to have little space along the y axis, therefore I needed a 90° cable cover. After printing MIKEYMCC's large version (to have some space for those crimp terminals), I actually measured the necessary y space for the first time, and found that that cover would still be too large by about 15 mm. So I had to start designing my own. Big thanks to MIKEYMCC for providing the .step file In the suspect's lineup in the pictures, from left to right: - Prusa original straight cover - MIKEYMCC's large cover - my first attempt. A couple of corners lifting up, and the distances for the body and the strain relief not quite right - second attempt. Corners on the body fixed, but the strain relief was still making trouble - third attempt. Looks already useable, strain relief rotated 90° for printing - fourth attempt, with a bit of fine tuning. Nobody needs a solid 3.5 mm top shell :-) Upside: The cover really is only 20 mm deep. I don't think you can go shorter and still keep the cable strain relief. Downside: Forget about those fat red insulated cable terminals. You'll need to get a couple of small uninsulated terminals (3 mm hole, up to 1.5 mm² cable), some shrink tubing and two regular M3 washers (all available through Amazon/ebay). The usual precautions for wiring a potential fire hazard apply. Front view is still missing - I just saw while printing that the cover is sitting somwhat skewed, and I'd like to figure out why.
