Your model is bad.
It has no faces on the inside:
Also it looks like the normals are flipped where it joins:
If you're on Windows then Microsoft's 3D Builder app is actually pretty good at fixing broken models. On other platforms you could try something like FreeCAD or MeshLab, but they're a lot more complex. There's also online tools that can fix models. I've attached a fixed version (from 3D Builder) because I can't help but help 🙂
Blender isn't always the best at exporting STL models (CAD software is) so sometimes it works fine, sometimes you have problems. Sorry but I don't know enough about Blender to help try and avoid his happening 😞
