The AutoDesk products rarely have trouble exporting STL files. This one is an exception.
I can't tell if a cut/join/intersect went wrong but that top surface has open edges so the model isn't watertight. That forces the slicer to "guess" where the outside ends and the inside starts. The "inverted faces" were what caused the red top surfaces in your screenshots. When red if facing upwards it always means the model needs repair.
Here is a report from a site I use to check models.
I noticed that even though the model is right on the build plate that support is growing under it to hold it up. That's because you have a "knife" edge on the build plate side. The sharp edge is too narrow to slice so you get support up to the point the knife edge is wide enough to slice.
AutoDesk makes NetFabb which is an excellent repair utility. It's bundled with Fusion 360 and should be available for Inventor.

Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications

MS 3D Builder was able to repair the file.
