"In Use" Filament Inventory Control Tag

Companion to the “Open Box" tag: https://makerworld.com/en/models/826616

I have a decent inventory of filament and when a filament is in the AMS, I still keep the box around for when I'm swapping filaments. Because I don't want to be surprised by running out of filament, I wanted some labels that helped visually organize what filaments I was running out of.

This easy solution helps me check inventory quickly, so I don't have to pull anything off the shelf to check what's in the box.
