Screws are often used for support but currently they often do not tie in very well with the rest of the model. It would be great to have the ability to add like an attached brim of varying thickness every x number of layers. If you have ever used a one screw mount even with a raised boss for the screw you know that it is pretty weak. But if a 3 layer raft went out into the infill it would really help to anchor it.
