Quick printing 3D swatches that show how the color and highligt fall off on curved and flat surfaces of each filament, including slanted surfaces and overhangs and layer lines. A holder for up to 36 swatches can also be printed: https://makerworld.com/en/models/219668

Each swatch has a two-digit number that can be used in a spreadsheet to keep track of brand and filament type.

The text on each swatch can be customised inside Bambu Studio by right-clicking on a swatch and select Edit in Process Settings, and then select text_shape and use the Text tool to adjust the number.
