Not a bad angle. The glass in there is 1/16" or less from the metal. The left side is 1/4", but the right side has a bump for the wiring grommet and is very close to the glass. I will take more pictures later. Tesla engineering will look at it in two weeks.
Whatever it was, disintegrated, because all that was there was glass.
Also not sure how something could stay there, as the grommet "bump" is quite round in shape.
