Ah. Okay - so just run it through a repair service.
netfabb free repair service is here (you have to create a free account first):

Here's another service - drag and drop mesh repair service:

Also - don't use raft. Ever. It's an old technology that is only needed with obscure materials like PEEK and even then shouldn't be used.
Thank you for your time, I tried your suggestion, but the problem persists.
I also tried to remesh it with blender. Same results.
As this model doesn't have any issue as well as I don't have any problem to slice it. I think you have activated in your profil the option Mesh Fixes-> Remove All Holes. Uncheck this option to get the right result
Edited by CuqAn other origin to your issue can be in the section Experimental -> Make Overhang Printable

Thank you so much, this was the issue. I may have left it checked when I was toying around. 😄
Have a nice day!
@cuq - nice find! I guess we should have asked him for his 3mf project file!

Well I see no red in your xray view which is great. so it's the "normals". Each triangle in the STL file has a "normal" which tells cura which side of the triangle is air and which side is solid part.
I have 18 solutions but it would be easier if you told me what CAD you used. Or if it you got this from someone else.
