Opencircuit Extruder nozzle 0.4mm for 1.75mm filament - 2 pieces

A set of 2 nozzles with an opening of 0.4mm for printing filament in a 3D printer. These nozzles are universal and interchangeable with different sizes of the opening. A smaller opening means less filament flow, which in theory means better quality prints versus a slower print speed. The standard size is 0.4mm where precision and speed are balanced.
