Existing Open Source Designs

• A Design by the Youtube Channel "Becky Stern"
• The Anybox
• "Modular Ender Spool Holder (M.E.S.H) by delman83 (modular roller, not full drybox)
• A Video by the YouTube Channel "Thomas Sanladerer" Titled "How to keep your filament dry: Make a storage box!" (~11 Minute Watch)
• A Video by the YouTube Channel "CNC Kitchen" Titled "Filament Dry Box || How to properly store and 3D print Nylon, PC, TPU, PVA..." (~7 Minute Watch)

Minimum Viable Product

• Modular Units (A Single Spool Model, A 5 Spool Box, A 10 Spool Box, and a Rack mount (or some other rack/module?) unit)
• Optional Integration with an FDM Filament Switcher
• Integration with print farm software (perhaps integrated runout detection, logging of humidity/preventing printing while wet

Basic Design

Box

• Airtight Box, either ots, or something 3d printed, then finished, and perhaps resin sealed?
• O ring and top lid
• Optional mounting system (especially for the rack/mount version for HMCUs and Print Farms where organization is key

Dehumidifier

• Open Source Dehumidifier
• Preferably the "smart" one so temp and humidity data can be gathered and used

Spool Holder System

• Individual Roller modules, common axle?

Filament Ports

• See the "Anybox" Device

Backup Dessicant

• Would this be of use?

Heater

• Would this be needed, or would the VERY low humidity increase evaporation enough to make this not needed?
• May also be a time factor

Code

• See the code section in Open Source Dehumidifier

Internal Links

• Metal Enclosed Silica Gel Desiccant Module (Essentially a mesh / vented "brick" filled with Silica Gel based Desiccant that contains the desiccant, as well as allowing it to be Regenerated in an oven without other containers

    • Granted a Bulk Purchase of Silica Gel and a metal mesh trashcan etc may work better for less
    • Could also just have them in a cloth bag, then dump into baking tray
