adafruit Aluminum Extrusion Corner Brace Support (for 20x20)

This part is based on the adafruit part: "http://www.adafruit.com/products/1155#Technical%20Details"

Please note that the part specifications provided by adafruit do not cover all of the dimensions on this part, so I have used the average measurements of about 3 pieces to fill in the missing dimensions.
