Tefnut Filament Handling

A system for the management of 3D printer filament. Based on cereal containers as individual dryboxes for spools of filament.

Goal

The primary purpose of Tefnut is to keep filament clean of dust/debris to avoid jams and clogs, and can also help with keeping filament dry. I found there is too much air leakage in the system to maintain a low humidity long term without regular swapping of large amounts of dessecant. That being said, with regular swapping of large amounts of dessecant it is possible to keep each filament completely dry.
