0.8mm V6 brass nozzle for 3d printer

Each one is integrally formed by a five-axis CNC machine and then precision drilled; the aperture is precise, the inner diameter is smooth, the filament is heated evenly, and the flow of the consumables is good, so the printed 3D model will be more accurate and beautiful. Each one is the same blank and drilled directly. The aperture is not accurted, and the inner diameter is rough. This will affect the strength and appearance of the model.
