Bosch 23-18LI Trimmer blade

Work still in progress, blade model is not manifold.
Added 2 new versions of the blade, v4 has been tested the last week and is fairly durable unless you hit something hard, created v5 (untested) with added material around the hole where it usually snaps.
UPDATE: use v5, during today it has proven to be much more durable.
UPDATE 2: blade v5 with 45 degree angled position on the print bed and 100% infill gives better structural integrity. Seems like it survives hitting a branch or stone. Used
