I'm looking to replace a Push Button Wall Plate. I can't seem to find one that only has spots for three buttons. Most have six spots. (three sets of two buttons). These are standard size push buttons (like you see for lights in a house) which I don't believe I could replace as they are push buttons that open garage doors.
I'm looking for a cheap wall plate (preferably under $10). The common tan color or white would also be preferred. I've checked Lowe's and Home Depot and googled around a little, but can't seem to find a replacement. I've added a quick sketch of my situation.
