Dual V6 J_Head Hotend 1.75mm 0.4mm Nozzle Bowden Extruder Reprap 3D Printer

2 X E3D V6 Long Distance 3D Print J-head hotend &Single Cooling Fan for 1.75mm Direct Filament Wade Extruder 0.4mm Nozzle Description: V6 has the following advantages over V5: To reduce the heat sink length, thickness and diameter (shorter length is conducive to the stability of increasing the heat end), while increasing the number of fins, the heat end reduce weight at the same time, has better heat dissipation performance and stability. External rotation gas heavy joint for a built-in pipe clamp, further reduce weight and reduce the hot end length, also make the feeding tube more deeply into the hot end, feeding more powerful (pneumatic connector can only be inserted a small tube into the feeding, easy to cause the feed is not smooth and other issues). Improving the original heating block, appearance is more concise and practical, heating tube, a thermistor and aluminum block contact more fully, and thus more precise temperature control outstanding. Package Included: 2x E3D V6 J-head Hotend for 3D Long-Distance Filament Bowder extruder 2X cooling fan 2X Fan cover (One red, one blue) 2x Box
