This is a larger version of the 27-LED stubby flashlight except with 36 10mm-size LEDs. For now the bottom switch plate is designed for supporting four pushbutton switches (for activating four different 9-LED segments).
Both the LED and switch mounts are removable and are secured via a number of small screws.
You'll need to figure out how much voltage you'll be using and the appropriate resistor(s) for your LEDs.
UPDATE: I've included another bottom switchplate. This time it has openings for four rocker-style switches. Also I've found the holes are best suited for use with #6 sheet metal screws.
