Summary

This fits a Lidl Parkside 20v line strimmer and converts it to more of a brush cutter with a solid blade.
Prints without support.

The blade might sit a touch below the blade guard, and is probably going to hurt a bit more than the line strimmer if it hits you, and might be more likely to damage itself and things if it hits something solid. Probably stresses the motor a bit more, but it seems fine to me.
