In my experience, if I want to use something that someone else modeled, I expect to have to at least clean it up if not repair it. Due to the triangulation of STL files, it would be typical to have some clean up to do before you proceed to make modifications. I imported your STL and ran Thom Thom's CleanUp3 on it. It reports as solid although it's not a nice as I would like to see it. It should be printable as is, though.
Generally I prefer to model things myself so I know exactly how they are made. It's often faster to model from scratch than repair something someone else made, anyway.
Thanks for your feedback, I see what do you mean, However some things I want to modify are very complex in order to make from scratch 😞
In NUT example I uploaded before, yes, it is printable with Cura, but Solid Inspector 2 says it is not solid. The think is that I want to make a modification in Sketchup, and as I know, all kind of solid tools require obviously solid, in this case I need to close 63 borders, totally crazy...
What would you recommend me in this cases? making a NUT from scratch, make a screw shape, etc, seems to be complex, right?
Thanks a lot
