The Heatbed Cable on my MK3 was starting to sag and catch on the frame of the printer. So not wanting to pull it all apart I made a simple clip on support that does not require any tools or disassembly to fit.
There is also a version for the MINI, just choose the correct download file.
Simply print and push on to the current cable cover as in the pictures and it will keep the cable lifted.
A very quick print and install that could save your cable.
Use supports for the overhang. See picture.
