About this 3D model
This is a holder for the 8x8 LED matrix found at: http://www.sparkfun.com/products/682 It is designed with a crossbar as a standoff for the pins coming out on the backside. However, it is not absolutely necessary if printed at just the right size as the LED array will be snug in the holder. I made this in OpenSCAD, but lost the file, which I may include later if I get around to rewriting it.
