3D Solex Wanhao Matchless Nozzle - 0.40mm
This high tech nozzle ONLY works for Wanho with the All Metal Hotend upgrade.
The 0.40mm will finish a print 4-10 times faster than a standard nozzle, provided you can live with the added layer width, and a higher layer. Very popular for printing large objects or small low res models. It is made of brass with a multilayer hard metal coating.
