Screwless Filament Feeder - 1.75
I found filament feeders for dry boxes here on thingiverse, but didn't like how they had to be screwed on, which just added more holes into the airtight container. I came up with this design, which just requires one 5/16" hole. Place a 5/16" o-ring before the nut and you got yourself a solid, airtight seal. Files are included for the filament feeder and the nut. Use a 14mm socket piece to tighten. DO NOT overtighten or it will break. Grab yourself some 4mm OD 2mm ID PTFE tubing and place inside the filament feeder. It's simple and it's small. Share and post your makes! Comments welcome.
