This kit is a complete setup for 3D Printer Bowden Extruder. Main extruder body comes pre-assembled for your convenience. This is reliable and very durable construction and build quality is very good. Filament drive gear has very sharp teeth and will provide perfect grip. Extruder body was designed to be compatible with NEMA 17 mounting hole pattern but also with GEARED NEMA 17 hole pattern (geared setup not pictured here). With Geared stepper you can use 8mm bore drive gear instead of supplied 5mm drive gear. See the following note about drive gear bore diameter:
Please note - kit comes with 5mm bore gear by default, but if you would like to use 8mm shaft geared stepper with this kit - we can substitute 5mm bore gear with 8mm bore gear upon request (please, attach request note to your purchase).
