I have a part that experiences larger than average forces in some of its protrusions. It would make sense to reinforce walls, and in particular strengthen infill in those areas. But to save material and printing time, I would like to use thinner walls etc for the rest of the part.
Are there any tricks for how to do this, other than printing two parts with different parameters and joining them somehow?
This is Prusa i3 with slic3r.
