Parameter: input diameter 2.00mm; output diameter 0.4mm, out thread: M6, a set of 20 pcs printer nozzles and the outer surface is marked with a size, so you can easily identify the specifications of the nozzles. Applicability and Compatibility: Our nozzles fit for Monoprice select mini, V5 V6, Prusa i3, Anet8, Anycubic i3 mega, etc, compatible with all E3D V5 V6 1.75mm PLA ABS 3D Printers. Fit exactly like the original. Strict craftsmanship: Meafeng nozzle strictly follows making standard, Greatly extend its service life. The inner wall adopts arc structure reduce the pressure required to extrude the filament, Can quickly flatten the filament that achieving improve the stability of the entire nozzle and print quality. Precision Process: Made with centering CNC precision automatic lathe and one-time forming technology, make sure the input and output holes are concentric and the interior of nozzle is smooth without burrs. Due to all of above, not only reduce the resistance, avoid blocking of the filament on the rounded chamfer, but also provide a long service life, make out of filament more smoother. Precise Design: Cutting with the diamond knife, make the contact surface more flat, so it can prevent printhead from leakage effectively and avoid nozzles clogging.
