It's a six-sided die. Each side is 1 in by 1 in. I made to to learn how to build things in 3D.

I used http://www.makercase.com/ to generate a 1in by 1in box.I then used Adobe Illustrator and added dots to each side.

The box was cut on 3mm acrylic on an Epilog Mini 18 Laser with the following settings:
Raster speed: 100, power: 60
Vector speed: 10, power 100, frequency 5000

The box was glued together using acrylic glue.
