This is a new, unused Outlet Fitting compatible with all Gen 2 Markforged Desktop Series and Industrial Series 3D Printers.This fitting connects the bowden tube to the plastic extruder, NOT the extruder to the load tube.This fitting is only compatible with the A3648 plastic extruder, NOT the Gen 1 A1095 plastic extruder.I no longer have a Markforged print farm so all parts must go!Markforged does not offer this individual component to customers, but rather forces you to purchase an entire Plastic Extruder at a crazy price.
