This is sized to be used on a Ford Maverick starter button.  The ring is a press fit so no adhesive required.  No supports required for this print.  This was modeled in Onshape, and I will share the model for anyone who'd like to resize this for their vehicle.  My thought was, what would happen if the engine is switched off by an accidental push of the start/stop button.  Got a good laugh when my wife said it looked like a mini toilet seat.   The hinge requires a small bit of 1.75mm printer filament act as a pin.
