No returns on this item
As you install a new nozzle onto a MakerGear hotend, a small amount of material is removed from the nozzle to create a custom fit. This makes the nozzle incompatible with any other barrel due to the slight variations in tolerances among different barrels. Unfortunately, for this reason, we do not allow returns on any MakerGear nozzles, regardless of whether they have been installed.
