I use both Lock & Lock and PrintDry containers to store my filament, and Vesken Shelves to keep them organized. Neither of the containers touch the bottom of the shelf and both have a raised lip, which causes them to tilt, so I created these to make them stand upright.

Note: the height of the Vesken legs is slightly too short, so it's a tight squeeze when placing and removing the containers. To fix that, I've created a 1cm riser. I've also created a Filament Swatch Band to easily identify the filament colors and where they go.
