This was my very first lasercut projects that I made during one of the FabLab open house sessions.
I first made a 2 layer holder for 3x9Volts batteries where the batteries fits like a glove. I then decided to play around with acrylic bending and made a flaming case for my arduino. The case just looks cool but has nothing practical to it since it makes the access to the output pins more difficult. I normally use this Arduino together with a prototype shield to "burn" other arduino chips like the ATtiny85.
