PrusaSlicer using bridge infill instead of solid
I am trying to print this connector which has 3 horizontal sides that have to be supported.
The trouble is that PrusaSlicer doesn't consider these bottom layers and uses bridging instead of infill.
How can I change this behaviour?

Typically it's a shell issue. And something to do with how you assign face normals in your CAD tool when making the part manifold. Anyway, I find multiple shells easily confuses Plicer and it can help to ensure something in the design makes it obvious to Plicer that the surface is an internal or external perimeter, like a small hole into an intentional interior void; or I'll remove the surfaces that tend to confuse.
Think of two intersecting cube shells. What is the inside of the intersection? Hollow, or solid? And how would a slicer know how to treat it?
ps: the sliced view doesn't really show what you are fighting, uploading the part or the part view might help. ZIP the stl before uploading.
