UM3, Cura 3.2, 0.25 mm printcore designs not slicing properly, help?

· UM3, Cura 3.2, 0.25 mm printcore designs not slicing properly, help?
You have a lot of choices here.
First of all, you modeled infinitely thin walls in sketchup so that's what you got. Infinitely thin walls. But I know that's not what you wanted (or maybe I'm wrong - maybe you modeled 0.25mm thick walls in which case read the next paragraph).
One choice is to model the walls in sketchup - make them 0.25mm thick. This is a reasonable option. Then make sure you check the box in cura for ultra thin walls and you probably want to set your line width less than 0.25 - maybe 0.22 so cura will be happy and your quality will probably be better.
However if your part will always be like this - no holes through the walls - no top or bottom - then much better to model it as a cube (by the way, everyone should have a cube.stl handy - you can add it to cura and stretch it to any height/width/length with the scale button). Then when slicing tell cura 0% infill, walls at 0.25mm and disable top and bottom infill. This will give you a much thinner result and it will happen on only one pass. You can even set line width down to 0.2mm and the quality should be fine if you want really thin walls.
Often getting started is the most difficult part of any process. A good start sets you up for success and saves you time and energy that could be spent elsewhere. That is why we have a onboarding course ready for
Ultimaker S5 Pro Bundle, Ultimaker S5, Ultimaker S3 Ultimaker 2+ Connect.

Oh and if you are going to be using sketchup to make 3d models (not the best choice but hey - it works) then you need to read this:
