If the point is to make a plastic switch cover, why is it important that the person CADs it themselves, rather than hitting print of a model they found online? Does it fail some sort of piety test that the end result that comes out the other end is a functional piece of plastic in a specific shape?
You just made that number up. The Internet is really big and there are many people on it. I could just as easily claim that you'll find something close enough 99% of the time.
