A filament swatch that I remixed mainly for my own use but decided to share!
I altered the proportions of the original to be able to use common and cheap 50mm x 30mm (1.96 in X 1.18in) Barcode Labels. I use these ones on amazon along with this printer. In addition to being able to reference a filament's color this swatch allows you to test how a filament handles overhangs, bridging , and wall thickness. The label also contains information such as brand & color name, printing temps, and a barcode to order more.
With the X1C, P1S, and P1P and Print Sequence set to ”By Object" in Bambu Studio, you can print up to 3 of these swatches in different filament without the need of a purge tower and without all the AMS waste.
I strongly recommend printing on an easy to release plate such as the textured PEI plate to minimize the risk of damaging the thin section of the swatch. Make sure to print at 0.2mm layer height to produce accurate layer thicknesses.
