I show how I used Draftsight, a free 2D CAD program, to design a custom case for a Raspberry Pi. I then use that design to manufacture it on a CNC router!
I also mounted my webcam to the gimble of the CNC Router, and captured some awesome first-person footage of it cutting. I could watch this video for hours at a time.
What are your favorite cases for the Raspberry Pi? Leave them in a comment below!
