Thingiverse
These cheap strimmers all come with this style of plastic blade. They brake really easily. I printed mine with PETG and found it lasted better and cost about the same as buying them. I would increase the wall loops to 10 or infill to 100% to increase strength. WARNING: When these break (same as the original ones) they release very sharp parts flying, wear eye protection and sturdy clothing.
