the plugin and repairs worked cheers gr5

im using blender, and it is non manifold but the area it shows isnt where the errors occur. ill try the plugins and i wouldnt think it the walls are to thin as the cannon prints fine in the first image. thanks for the help and advice. es cannon part.stl

I'm new to cura and I've been printing for about 3 months with it and I've recently come across an issue when slicing a model, its seems to remove/ delete parts of the outer area of parts of the print on one file but then on a more complex version of the file it doesn't and the sizes are the same, its stumping me why it is doing it. sorry if not clear from the images.
