Filament Roller

thingiverse

I notice that printing out of a drying box over the Neptune's spool holder causes tension on the filament as it's being pulled out from the box. I created a simple roller that relieves tension as well as allows some play as the filaments are feed through. You can use multiple roller to feed different color filament when switching color in-between. You still need to manually load and unload the filament. Made it for Elegoo Neptune 3 Pro, but should fit any 3d Printer that have a filament spool holder.
