Filament Guide For Airtight Box

thingiverse

This guide screws onto the outside of an airtight filament storage box. It is threaded for a 1/4" NPT Quick Connect adapter, allowing you to attach a hose and guide the filament through it directly to your printer or however you need. The center hole in it is large enough for 1.75mm filament, designed to minimize scraping. You can put some non-lint microfiber towel or sponge inside the Quick Connect adapter/mount, which will act as a pre-filter pulling some dust off the filament.
