....or perhaps: model a solid rectangle (without holes), in Cura choose a wall line count of 1, zero top layers and zero infill.
Should also print nicely.

Hello @sibianul, I'm just going to answer your first query about the nozzle movement when printing the thin walled square. Cura treats that model as a solid object that has a hole in the middle. OK, so the hole is nearly as big as the outline but that makes no difference, it's still a solid with a hole as far as Cura is concerned. So Cura prints one wall which is the outline of the model and then another wall for the hole (the inside of the square). Because the hole is almost as large as the outline, the two walls are very close together. So close that they overlap. There is a Cura setting called something like Wall Overlap Compensation and when you enable that it reduces the amount of plastic that is extruded when printing a wall that is so close to an existing wall that they overlap. If the outline wall and the hole wall are really close together, the overlap compensation will reduce the flow for the second wall to almost nothing and so it ends up as little blobs which looks crap. There is another setting called something like Minimum Wall Flow that is a min percentage of flow that any wall will have. Walls that have a lower percentage flow than that value will simply be omitted. So.... to get a nicer print, make sure you have the wall overlap compensation enabled and set the minimum flow to something like 20 and your rectangle should print nicely. Hope this helps!
