Dry Box Storage System for 3D Printer Filament, Updated for 2024 and Better than Ever!

I'm always on the lookout for good ideas when it comes to storing spools of filament and keeping them dry, and I've finally landed on a solution that is perfect for me.

This system is heavily inspired by a design from Stephen Wardlaw. His original design and YouTube video can be found here:

   • Filament dry boxes for MMU printer  

I've combined Stephen's design ideas with my own past iterations on filament dry box solutions to come up with the system that I show in this video. All the files needed to print the parts required to assemble one of these dry boxes can be downloaded here:

Below are Amazon links to the storage containers and other hardware bits that I used for assembly.

If you try out this dry box design and have suggestions or feedback, please reach out either here in a comment or on the post at Printables. My plan is to continue iterating and improving this design, and also to create an ecosystem of useful accessories to make using these dry boxes easier and more enjoyable.
