I made a filament swatch for my filaments. I've recently almost run out of a couple colors of my originally purchased filaments back from 2015 and wanted to create a swatch for cataloging it for myself. I tried to add everything I could think of, radiuses, holes, sharp corners, overhands, and a .5 thickness area for transparency.
I included the file shown here for AIO PLA as well as a version with no text, and even a OBJ file for easier editing, enjoy!
