This Diamondized Nozzle by NANO M&P for 1.75mm filament is an upgraded nozzle that replaces your current nozzle for your 3D printer's hotend. They last longer and print smoother than original nozzles by preventing jams and lengthening your need to replace your nozzle. They are easy to clean, maintain, and work great with all TVF filament.
