Compact 5-Spool Filament Drybox

This filament storage system is built around a Sterilite 30 liter water resistant box. The drybox will store and feed five typical 1 KG spools (e.g., Hatchbox, Amazon Basics), keeping them dry and dust free. This is part of my compact 3D printing workstation (https://www.thingiverse.com/thing:3399360).

I designed threaded rod supports that maximize internal space, as well as a plug that serves as both dust barrier and quick access filament end holder. Some good part designs by others are used for this project and linked below (thanks to @rainreign1 and @Flex35).
