arameter: Inlet diameter 2.00 mm, outlet diameter 0.4 mm, M6 thread. And the outer surface is marked with a size, so you can easily identify the specifications of the nozzle. Applicability and compatibility: Our nozzles are suitable for Makerbot Creality CR-10, MK8 Makerbot Reprap 3D printer Prusa I3, compatible with all 1.75mm PLA ABS 3D printers. Fits exactly like the original. Precision Process: Manufactured with a precision CNC automatic lathe, ensure the entry and exit holes are concentric and the unique forming technology ensures that the inside of the nozzle is smooth without burrs. All of the above not only reduces resistance, avoids filament blocking on the rounded chamfer, but also provides long service life, makes filament output smoother. Precise design: using diamond knife cutting, make the contact surface flatter, at the same time, you can effectively prevent print head leakage and avoid nozzle clogging.
