This extruder end kit is original-part from for Creality Ender 3 V3 SE 3D printer. It has been assembled in advance and the wires are directly plugged in, allowing for quick replacement. High precision thermistor, temperature detection up to 260℃. Say Goodbye to Clogging: Heating Block + Heat dissipation block, Highly effevtive heating and heat disspation, Fewwer cloggings, much higher printing success rate. Rapid Heat Dissipation: Irregular wave structure design increases the effective heat dissipation area and realizes fast heat dissipation. All-metal design for better overall performance Silicone Cover is provided to help keep temperatures on the for Ender 3 V3 SE end much more stable and this will result in higher print quality and consistency.
