Dry-box filament pass through, with filter

thingiverse

Three part Filament filter and pass through for your dry box designed to minimize filament contact with air. The "outside" component is designed to go on the outside and is threaded for an M10 pass-through PTFE fitting Center/Filament filter component is optional and can go inside or outside the box (I think Inside make more sense) with a dish removed to allow for a sponge to drop in as a wiper/filter Inside component goes inside and has slots for M3 nuts. (The outside piece is counter-bored for M3 socket cap screws) All "feeding" surfaces are angled to help feed filament though initially (with a centering cone in the outside bore to butt the PTFE into) I designed this with my Prusa MMU2S in mind, but it should be compatible with most printers/feed systems. Also required to build: * 2-6xM3 socket cap screws, just don't drill holes in the box you won't use (length depends on thickness of drybox wall, minimum will be about 20mm, I recommend 25-30 and trim if needed) * M3 nuts, count depends on how many screws are used.
