Personally I printed with 0.6 nozzle, and at least 3 outlines so wall's don't end up with a line of fill in the middle.. prints so much better.. if using 0.4 I would add more outlines..
I also printed in PETG I don't mess with PLA much..
only change -1 to -2 is the radius on -1 is little to small so there are gaps.. I need to print 2 and see if I corrected enough or to much.. but V1 does hold x20 very well
