Micro Swiss FlowTech Hotend for Elegoo Neptune 4 Plus and 4 Max

The Micro Swiss FlowTech hotend is a drop-in, all-metal upgrade for the Elegoo Neptune 4 Plus and Neptune 4 Max, made in the USA. It is a plug-and-play kit with a heater core, thermistor, and heatsink, so stock z-height, build volume, and firmware stay the same. The nozzle and thermal break are a permanently sealed assembly for leak-proof performance, and nozzles can be changed cold, with one hand, without hot tightening. A ceramic cylindrical heater and 28.6 mm melt zone give high-flow performance, and the hotend is rated to 300°C. The kit includes a 24V 60W FlowTech heater core, copper thermal adapter, brass-plated 0.4 mm nozzle, two titanium mounting screws, a heatsink, a 30 mm PTFE liner, and a silicone sock.
