Works most of the time in s3d: repair menu, flip surface orientation, then click on the object.

If you have a PC with Windows 10, there's a useful utility called 3D Builder. Load each part into this utility...and if there's any issues, the program will repair them for you. Then save as the default .3mf format.
If you don't have WIN10....then you will need to use one of the online repair services....eg Netfabb or MakePrintable. Google and you'll find a few.
This, unfortunately, is one of the risks of downloading free things from the internet!!!
I tried both solutions, still sliced model doesent match original, also i came across another issue, the model in S3D looks good but after slicing, some walls are missing or even worse, random chunks are added here and there. Its anoying cause you realize it after the print is done..
