This J-Head Hot End is assembled and designed based on other nozzle. It’s very simple by reducing the number of custom machined parts to a bare minimum. The J-Head Hot End can easily and well interface with the most popular RepRap extruders. The filament path is same with teh one of an already proven design it can be used to print reliably with both ABS and PLA. If using PLA it requires a small fan to provide air-flow through the cooling vents milled in the sides of the nozzle holder. Besides the Hot End has another two advantages. Heat transmission is more efficient as there is no thermal junction where a separate heater screws onto the nozzle. And a resistor is used as a heater. There is no need to wrap nichrome wire or to bake a heater core. Noted: Nozzle: 0.4mm Filament: 3mm With 75cm cables
