STL “are” meshes. If you don’t want meshes you should use a different file format.

Hello - - MeshBooleanUnion/Difference/Intersection are the commands to use but they are not all that robust - can you post the file?

-Pascal

Hello - the mesh is a block. ExplodeBlock and then use MeshBooleanUnion. You should make the small part fully intersect the mesh before the Union.
