Big prints, thick walls, or you just want the clock to stop sooner? A 0.8mm nozzle pushes more filament per pass and your print times drop fast. The catch with stock brass is it wears down and starts clogging before you'd expect. This hardened replacement holds that wide 0.8mm profile for a lot longer. Drops straight into the Creality Neptune 4 Plus or Neptune 4 Max hotend – no adapters, no fiddling. Swap instructions are included. Change it in, raise your flow, and get back to what you're actually making
