E3D Thermistor Cartridge

Make sure you tape the thermistor heater extension connection and the block heater extension to the soldid mount on the back of the printer head where the cable connects . This is a solid piece connected to the printhead and does not twist when the head moves in the X axis across the bed width. If you only tie the thermistor and heater connectors to the cable, the twisting motion eventually wears out the insulation of the thermistor and heater tube wires at the entry of the heater block and shorts out.

Works as intended. The length of the cable is just barely long enough to fit the Ender 3 V2 so if you want extra length for any reason you may need to extend the wires. The quick release connector near the hot end rests perfectly on the top of the stock Ender 3 V2 fan casing.
