printed ignoring thin wall infill. Looked best yet, still some rippling at the bottom but it didn't print another perimeter inside now matter how high I put the overlap. It's a part that is 1.5mm thick and a .4mm line width, should easily be able to fit a third in there but I guess it won't do it unless it can complete a full rotation or something.

So I went back and put the gap fill in and lowered that gap fill overlap to 5%.

We shall see
