3D Filament Tags

I have been storing 3D printing filament in Home Depot 5 gallon buckets with screw top lids with O-Ring seals and color changing desiccant. Each holds 5 1-Kg spools. I find myself opening several buckets to find the filament that I want to use. I decided to create tags which clip on to the handles of the buckets that identify the type and color of filament when printed with the actual materials.
