Raspberry Pi
The Raspberry Pi is a credit card sized Linux computer that sells for $35. The Raspberry Pi Foundation released their CAD files in the step format. To keep prices low, they sell the board without an enclosure- this is great for product designers as we can design custom enclosures for it. This is a concept housing for the Board B, the latest release from the Raspberry Pi Foundation.
An update on this concept is following shortly based on feedback from the Pi community.
