Filament Box Feeder

thingiverse

Hey guys, I wanted to build a filament box and used some designs of feeders to get the filament out. I wasn't quite satisfied with the versions that were available, so I made my own. The feeder itself is from Amazon: https://www.amazon.com/SIENOC-PC4-M6-Pneumatic-Fastener/dp/B06XXCJ8TB/ref=sr_1_3?ie=UTF8&qid=1533655077&sr=8-3&keywords=pc4-m6 I used some PTFE tube, which fits perfectly. In my version, the feeder is held by an inside part that keeps it in place. Both parts are fixed with M3 screws (round head with a hex wrench). The nuts should fit into the inner part. I make the box airtight by using double-sided tape on both parts. It works like a charm!
