This includes the hardware pieces needed to upgrade the MK8 Basic extruder to the Flexi Plus model.
1 x threaded stainless outfeed tube with beveled end
1 x thick jam nut
1 x 11 mm round body stainless coupling nut
This is the latest hardware.
UPDATED: 12-8-2017 This update includes current tube design with conical end. The shape was changed from a wedge to cone shape. This allows for easier adjustability, should you want to.
