I'm not storing my filament in The Ultimate Cereal Container Filament Drybox - Official Remix by GunplaMark | Download free STL model | Printables.com all the time, just when they are in use. So I wanted a way to organize the labels that are not in use currently.

Quick little project to create this tray - labels are easy to view, can flip forward to see the ones behind better, and are stored compactly.  Spacing is loose to make them easy to insert.
