concentric infill only on thin walls

[spacevan]

What I want to do is avoid having the infill wiggle back and forth so it is easier on the printer. I have attached the factory file so hopefully someone can help.
The original wall thickness was .8mm I uniformly scaled the print by 1.95 so the wall thickness should be 1.56mm I have tried multiple adjustments but cant get it. in the past it has worked for me to divide the wall thickness by the number of outlines I have set and then adjusting the extrusion width accordingly eg. 1.56\4 =.39mm. so 4 outlines at .39mm should equal the wall thickness with 100%infill. I have also tried selecting "only using perimeters for thin walls" and then adjusting "allowed perimeter overlap to 50% and that works with the main part but the other piece has gaps in its perimeter walls. And it increases the print time by a couple hrs. I'm shure that i'm just missing something because it would be a lot easier on our printers to avoid having the infill wiggle in thin walls when it could be concentric. Any help would be great thanks

I was able to set Thin Wall Behavior (Advaned tab) to Only Use Perimeters for Thin Walls and set the Overlap to 50% and it only used perimeters.

yea I could get it to work that way for the main part but then the smaller part the cap was missing infill. I know that I could add another process but when having perimeter over lap at 50% it adds another 2 hrs to the print. I was hoping that I could select only use perimeters for thin walls and then select auto extrusion width and the program would automatically print any walls within a certain thickness only using perimeters and achieving 100% infill, a strong print, and easier on the printers. This would be useful for a lot of prints ex. cookie cutters thicker vases this print ect ect.

I have always thought that "overlap" was only for the infill to overlap into the perimeter (to get the infill stick to the walls),
but does it also make all perimeters print closer to each other?

Disregard above. I was thinking of infill overlap..
