Update: Newer versions of this outlet extender have a recess in the back so they now fit properly against the wall.
These models are spacers to fill the small gap left by a 5 Outlet Extender (see link below) between it and the wall. There is one that is straight and one that angles to match the slope of the unit's sides (both have now been test printed). I modeled them to fit around my existing outlet plate, but STEP versions are included to allow for easy customization.
Two walls and 10% infill seems to work fine.
