mower blade disc for Gardena R40LI

160 mm mower disc for gardena R40LI/R70LI
based on a model from eglimrd1 on thingiverse (https://www.thingiverse.com/thing:3876233), modified to use M4 heat inserts (ruthex)

needs a larger protective shield, I used https://www.thingiverse.com/thing:2963014

I used the original screws and blue loctite

update: added sacrificial layers, no more supports needed 

I printed this in TPU this season and am pretty satisfied. printed with a lot of walls and infill,  it is tough af.
