Rocker switch mount

I needed to make a holder for my rocker switch that powers the off road LED lights on my truck. Originally I just cut out a hole from below my dashboard and stuck in in, however it continued to pop out so I hot glued it in place, well, I live in Arizona and after a summer of heat the hot glue didn't hold up. So I designed this holder so a standard sized automotive rocker switch could snap into place securely and so I could use two self tapping screws to drill it into the plastic.
