yet another rubbermaid filament spool chumpy

thingiverse

I've started using BVOH in my MMU and wanted a well sealed box that could feed right into my filament bank while keeping my filament dry. This model seats a spool inside of the box with a feed hole for PTFE tubing. It will work best in situations where the spool is on a shelf above a printer or filament buffer. As with many of these types of designs, it all starts with the Rubbermaid 21-Cup Dry Food Container. I've been successful feeding the filament into the horn even while the filament is in the box. I've included [Vincent Groenhuis'](https://www.thingiverse.com/VincentGroenhuis) amazing spool nuts from his [Universal Auto-Rewind Spool Holder](https://www.thingiverse.com/thing:3338467), which the hub of my design is intentionally compatible with. The rewinder didn't really work for me, but I had a bunch of those printed up so reuse made sense. I've included the OpenSCAD files (although I'm not especially proud of the code) and hope that other people will be able to improve on the design.
