Light switch cover, extra large

I live in a really old house and had a light switch put in. Unfortunately the hole in the wall was too big for a standard size cover and the hole was going to be really annoying to fuss with. Needed an asymmetrical oversize cover.

I uploaded the SketchUp file so that it can be adjusted to what you need. The switch opening and screw holes are universal, so keep that in mind when you adjust the plate dimension.
