4X4 button keypad housing

This is a housing for those inexpensive 4X4 keypad boards used on various Arduino and Raspberry Pi projects. These keypad boards have no mounting holes so I used tabs to hold the board in place. The integral buttons in the top cover are a bit taller and wider than the buttons on the switches making then easier to use.
Since this is a work in progress it's not quite perfect but hopefully someone will find it useful.
