As John highlighted, overhangs can be messy, recently with my own designs I've added hollowed sacrifial blocks underneath with a 0.2mm airgap and connected it to the chassis with a 0.5mm block so it renders as a single item so the slicer doesn't move the bits around. I don't use supports for this. The thin connector snaps off leaving a little bit of polishing to do.
