For Avery 1"x2-5/8" labels such as 5160 used by 3D printing filament swatches such as this and this. (I'm using the latter, which includes filament type in the print, so I'd put filament type in the notes if at all. Usually just filament type details, if any.)

sudo apt install -y ghostscript
pip install -r requirements.txt

python main.py example.yaml

Takes YAML list of filaments:

- brand: Prusament
  color: Galaxy Black

brand and color are required. The others are optional:

• url: added as a QR code
• note: smaller font, and on the third line.
• note2: smaller font, and on the fourth line.
• color2: same font as color, but on the third line. Good for overflow.
• color3: same font as color, but on the fourth line. Good for overflow.
