Vizio XVT553SV "clip in" phone/camera mount

I designed this platform for use with a car phone mount/holder so that my phone can be held/mounted on top of my TV for use during video conferences. This design will slot/clip into the venting slots in the top of the Vizio TV (XVT553SV) with a slight interference fit so that it is securely held in place.
The top plate must be printed on a very smooth surface with very good and full first layer otherwise your car mount's suction cup may come loose.
Required hardware:
(4) M3x10 machine screws
(4) M3 nuts
(4) M3 washer or lock washer (optional)

This design worked very well for me but after a week the suction cup peeled away so I added a rubber band to reduce the moment and keep the back side of the suction cup from peeling off. If I were to make another version of this I'd add a hook to the plate part to more easily affix a rubber band. Even if your top plate print is very good adding a rubber band is a good safety measure so your phone doesn't fall.
