/diy/ - Do It Yourself

I'm slicing with cura.
Does anyone know of a slicer that gives you more control over fine details of slicing? For instance in the gif I have a small detail that needs to be solidly attached to the main piece. But cura decides that it should make a hole in the shell and keep the infill running throughout the part into this smaller piece rather than making a solid top layer and then printing a new set of infill ontop.

Right now my only option would be to fix this is do 100% infill, which would be fine here since it's just a test piece but for the real application that's not preferable.
