If a smaller nozzle brings the layer back then the problem is that the walls are too thin.  Period.


Normally the wall needs to be double the line width setting.


You can get away with thinner than this if you check the "print thin walls" option in cura.  Did you try that?  You still are limited with how thin you can go versus nozzle size.  You can thicken your thin walls in cad or you can use "horizontal expansion" to make everything thicker or you can use a smaller nozzle.  A 0.4mm nozzle usually prints reasonably well down to about 0.3mm line width.

Yes, I turned on 'Print Thin Walls' and it worked! Yay! Thank you!

    This thread help me a lot. 


    A client sent me a model and swore his design was 'watertight' but Cura  and Mesh tools said no.  I looked up non manifold and found something to look for .. LOL



    In the end i opened up his design myself and sliced it in half with my CAD program and sure enough there was two edges just like this example



    he adjusted his design and all was well in Cura.

    i try to use the mesh tool to repair but my cura keep on crashing & not responding. please help



    This happens to me, too. If your file is somewhat greater than 5 MB or something, it starts to get laggy, and at around 10 MB, or again, something like that, Cura crashes because I think, and this is only an assumption, that it reads every triangle on the file and fixes the ones that need to be fixed, so more triangles mean more work. That's just what I think, I'm probably wrong. If Cura crashes, then, I just use Meshmixer to make the object solid, or just leave it be, and if it really needs to be water proof, then I'll just add some layers of epoxy or another waterproof substance inside to block water from coming in or out. When your model is not manifold, it doesn't really mean anything, only that, well it's not waterproof, so get it fixed in Meshmixer or add some stuff later. I'd suggest Meshmixer since that's a helmet and you're gonna be wearing that, so it would be pretty hard to breathe it. I'm not that good in Meshmixer, so for me, there are artifacts which make the item less detailed, but maybe you can find a way around it.
