yet another rubbermaid filament spool chumpy

thingiverse

I've started using BVOH in my MMU and wanted a well-sealed box that could feed directly into my filament bank while keeping my filament dry. This model seats a spool inside the box with a feed hole for PTFE tubing, making it ideal for situations where the spool is on a shelf above a printer or filament buffer. 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' amazing spool nuts from his Universal Auto-Rewind Spool Holder, which 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 and hope that other people will be able to improve on the design.
