This is a quick and dirty strain relief bracket for all the wires coming off your extruder to prevent them from getting bent and jostled as much when the carriage moves around. Tested with a Greg's Hinged Accessible Extruder, but it'll probably fit any extruder design with an exposed motor.You'll probably want to print this in ABS, seeing as how the bracket contacts the motor's surface. Also, that'll make it flex more easily if you want to slip this over a motor that's already attached.
