The Solarbotics Arduino Freeduino Enclosure (SAFE) is a laser-cut acrylic case for your Arduino Mega. It also has the added feature that it can house an Arduino or Freeduino instead with a MEGA amount of space left inside.
Originally intended for the Arduino Mega, this marvelous contraption of laser-cut acrylic can alternatively be used as an enclosure for your Freeduino, Arduino UNO, Leonardo, or Duemilanove if you are looking for more space inside your enclosure. Pushing out the acrylic knock-out for the USB jack is all you have to do to make the Duemilanove, UNO, or Mega fit nicely. This stylin' box even has room for a shield and a half (depending on size) on top of the Mega for making application-specific projects that can be neatly stored.
Oh, and every Mega SAFE includes an external switch lever that mates with the power switch on the Freeduino SB - way cooler than cutting power wires every time you want it to turn off. The kit also includes 4 x #4-40 bolts and #4 spacers for threading the Mega down onto the acrylic base, 8 x #4-40 bolts & #4 Nuts for holding the enclosure together in the T-slots, and 4 little rubber feet.
