How would I go about fixing an STL file for a model which has thin sections on it? Example, think of something like a cookie cutter, where the "cutter" part is only 1 perimeter wide. Say I wanted to make that edge print with say 4 or 5 perimeters instead... how the heck can I do that without having to re-do someone elses model entirely? I can print it with the "detect thin" option, and get the 1 layer printed, but that's not enough... it's still FAR too thin, and I'm finding parts of it isn't even printing because if the layer starts there consistently (the "Randomize Start Point" option in Slic3r is an effing joke!) I end up with really mixed result printing. I just don't know what software I can use that'll actually allow me to fix this easily. It seems such a trivial issue but I'm totally stuck here.
