Elegoo Neptune 4 Pro FIlament Rack and PTFE Guide.stl

This is a simple and very effective way to roll and guide your filament into the extruder. It requires. -The two 4mm bolts already supplied for the stock filament rack and then you can either use two 4mm self tapping screws or two 3mm heat set nuts and bolts for the bottom panel that locks the guide on the machine. Or just use glue, your choice. -Two 22mmX8mm bearings for the roller. I'm happy to answer any questions you may have : )
