E3D Prusa ObXidian MK4/XL Nozzle 1 pcs 0.4mm

>These high-quality 3D printing nozzles are designed specifically for use with Prusas latest extruder – Nextruder. Compatible with Prusas MK4 and XL 3D printers, they feature an all-metal filament guide which means that Nextruders filament path is entirely metal. With a wear resistance that is orders of magnitude higher than any other E3D nozzle, ObXidian is really hard, making it the perfect nozzle for printing abrasive/filled polymers with. This is achieved by pairing a tool steel insert with our new E3DLC coating. This specially formulated coating also embeds non-stick properties into the Nozzle itself. Meaning considerably less plastic build-up around the Nozzle. E3D
