grass trimmer replacement blade

after a few attempts, this version was created. i wanted a replacement blade that also works with PLA. by reinforcing the critical point to 3mm, a higher stability is achieved. due to the reinforcement, there is a higher weight. please try it with grass trimmers with only one blade, because an imbalance can occur.

there are 3 versions, as there are different Ø of the retaining bolt - 5, 6 and 7mm.

the best experience i have had is printing with fill 100% and concentric, but top and bottom normal with lines.

please be careful when trying out, as high speeds are reached. please wear safety glasses.
