Hi all, a little more detail on the neon covers. I made two subspecies for each species. This is necessary because of the different wall thicknesses (see picture).   If you install a regular cover plate on a angle (diagonal) wall on both sides, you get an unpleasant visible gap.   And windows in general on diagonal walls expand. That's why I created a separate subspecies for diagonal walls, it is marked with a black triangle with the letter A. And a little video
