3maker J-head Extruder Hotend Copper Volcano Nozzle 0.4mm for 3D Printer 1.75mm Filament
These nozzles have the same dimensions as the stock nozzle. No idea as to why the product title has “Volcano” in it. This is far from the length of an E3D Volcano nozzle.
The nozzles above are not the same length as the stock. I thought I measured the nozzles before using them. The threaded side is 1.17mm shorter than the original.
The stock nozzle has an overall length of 10mm. The threaded side is 5mm making the output half also 5mm. The threads are M6x1.0 and the nozzle opening diameter is 0.4mm
