Remixed Jeep vents for Miata, easier printability

there are 2 styles of vent, the original shape by Simon Jin, just made a bit easier to print.and my addition of a inner ring that rotates slightly easier. be aware once its pressed in, it is pretty permanent.the inner ring also has additional clearance for the filament axle to be melted into no supports on the main body, some on the flap for the center pivot.lay all faces flat, the “arrow” inside the axle holes, should face upwards.
