weed eater blades

I bought a Push-N-Load 3-Blade Universal Trimmer Head and eventually needed blades. Yes i could just go to the store and buy some (boring). Or i could find a useful idea for all those small filament spools. I hate wasting things, so this seemed like an idea to get the most yield from a spool. Besides, pla is "earth friendly".
