Bolt on Filament Feed Port specifically for the Flashforge Adventurer 3 and Monoprice Voxel. Will work with other enclosed printers as well. 

A template to make the cut through the plastic door/housing is included in a separate file. This part doubles as a face plate for the exterior to clean it up. A second plate with a cutout is included. This allows the plate to slide over filament already running through the port if you decide to print later. 

Holes in the faceplate are for M3 hardware. 

Holes in the feed port are for M3 brass inserts OR will support M3 nuts with washers. 

STEP files produce better results and higher polygon counts in PrusaSlicer. Both STEP and STL are provided.
