Filament Box Outlet

thingiverse

filament outlet/tap for feeding through a filament/dry box. snugly fits 3mm OD PTFE tubing if you want to keep your filament controlled from box to extruder. please note, this is for 2mm ID/3mm OD tubing, NOT for 2mm ID/4mm OD PTFE tubing. why would i use this instead of standard PTFE? because you can get 5M of 2/3 for $6 on ebay, compared to 1M of 3/4 for $10. and from the box to extruder, do you really need thick wall? and pc4/m10 fittings on a F'ing feed box? the tubing should slide in by hand & stay under normal use. there's enough room inside the cap to grab on to & adjust the tubing to pull in/out. https://www.ebay.com/itm/ID-2mm-OD-3mm-PTFE-F4-Tubing-Pipe-For-3D-Printer-1-75mm-Filament-RepRap-Rostock/392384921572 you can also use this as a box port without the tubing. i put the cap INSIDE the box so it doesn't get accidentally bumped. i only have 1 port & spool holder, which i change filament on based on need. seriously... who the F needs every single filament immediately accessible? the only thing i changed from the original design is the center taper (in the middle, so it's the same for inside/outside mounting) on the insert piece. but i'm posting the 2 unchanged originals so it's a complete set without tracking it down. again... please read... this is for 2/3 tubing... NOT STANDARD 2/4 PTFE!!!!
