I just ran across this video about replacing the bed heater cable stabilizer with a printed one that allows full travel of the bed spring in that corner. Also, a bracket for keeping the heater cable from rubbing on the power supply box. Plus a nice pulley to align filament going into the extruder.
Update I printed the bed heater cable stabilizer today and it doesn’t work. The wheel on the x axis hits the bracket when printing along the outside edge. It can probably be modified to work if anyone wanted to spend the time working on it.
