This is a laser-cut acrylic bezel for Sparkfun’s Monome-like Button Pad PCB and Button Pad. These 4×4 Button Pads are great: big chunky buttons with a PCB that can take an RGB LED. JMG is making a “monomuino”, a Monome work-alike using this pad and an Arduino. And he’s extending the Monome functionality since his indicator lights can display 3 dimensions of data instead of the normal 1 of Monome.

I’ve had one of these button pads for a long time but was stymied from using it for a variety of reasons, partly due to not having a bezel to stabilize the buttons from canting to one side when pushed. Sparkfun always seemed to not have their bezel in stock. So I decided to try to laser-cut a piece of scrap black 1/8″ acrylic into a nice bezel.
