I made a filament swatch card holder in credit card size (thickness with cover: 4mm), perfect for those who just want to keep tab on their filament colors in a simple way.

The swatch holder also includes a cover. You can fully customize the color of the emblem and the cover itself. I also made several covers with popular filament brands on them. The colors of the brand logos are customizable as well.

The swatch itself is 10mmx10mm, and i made a small chamfer on the bottom to compensate for the elephant foot. I also made 8 swatches, a blank one, and 7 others with labels of different filament types on them.

If you intend to print the swatches with the labels, I recommend that you print the swatch with the Wall Generator “Arachne” for a slightly better quality. If you wish for a nice matte finish, print everything on a smooth PEI plate, but it's not a must.

Keep in mind that the swatches fit nicely in the holder, but don't take them out and put them in too often or they'll become loose.

I printed the swatch card with the 0.2mm nozzle so i don't guarantee that it'll work with the 0.4mm nozzle.
