Fixed Enclosure mounted Filament Cleaner/Oiler

A simple filament cleaner and oiler mounted on top of your enclosure. If your spool is outside the enclosure this will integrate cleaning filament from dust before entering enclosure. You could mount an M5 pneumatic connector at bottom and attach a PTFE tube for better guide to the extruder. Only works for direct drive extruders.

This is for 1.75mm filament, but it should be fine to drill up the bottom hole for 3mm. You should drill the hole anyway for a little more play.
