Anycubic Chiron Strain Relief Bracket

thingiverse

I designed this Strain Relief Bracket after the thermistor cable of the heated bed broke twice and the cable of the heated bed itself snapped once. Breaks of the heated bed cables are a common problem on the Chiron. The reason for this is Anycubic using subpar quality cables and winding them around one of the coils of the heated bed, creating an extremely narrow curve. The thermistor cable doesn't appear to be much better in terms of quality. I suggest replacing all four cables with high-quality ones (using AWG 10 silicone-isolated, high-flexibility cable for the power cables). Important: For using the Strain Relief Bracket, it is crucial that you solder the cables exiting the heated bed and not entering from inside (this is the original position of the cables) - so you need to solder them rotated by 180 degrees. The bracket utilizes an unused hole on the base plate that the heated bed is connected to via springs. If you turn your machine, it will be visible. The screw I designed is optional; you can also use a M4 screw with a washer if needed. Printing and gluing an M4 screw might be easier, though. The four cables exiting the heated bed can then be secured by two zip-ties to the bracket. I recommend printing the bracket using PETG or ABS. The design may not be aesthetically pleasing, but it should effectively solve one of this machine's problems.
