when doing perimeters
think hollow sphere.
on the way up we want to do perimeters from the inside out.
but from the equator we want to swap perimeters to start with outer perimeter.
this of course applies to the angle in relation to the layer below. so the overhang is processed last.
alternatively always use at least four perimeters and start with center perimeter.
another good setting would be "enter perimeter away from overhang" where plastic have a tendency to warp upwards.
also if selecting 0% infill -> force infill at domes might be a good setting.
