Features: The 3D printer nozzle is made of high quality brass and the nozzle cleaning needle is made of high quality stainless steel. Heavy duty and long life. The 0.4 mm extruder nozzle is precisely designed to prevent print head leakage and produce consistent print results, smoothness and gloss. Reduce the resistance of the corners and avoid using rounded chamfers to block the filaments. The nozzle cleaning needle is very flexible and sturdy, easy to bend into a nozzle and does not break. Ideal for handling hot end nozzle blockages in difficult extruders. Suitable for 0.4mm 3D printer nozzles, including for Makerbot Creality / CR-10 / Ender 2 / Ender 3, etc. The needle is also suitable for use as a part of the nozzle. The products are exquisite in craftsmanship, easy to install and easy to use.
