Raspberry Pi Mount for 19CM Network Rack

A remix of SherlockWatson's Raspberry Pi Rack mount, changed to suit the 19cm Network Rack by Blinkinlabs.  Mounts with a couple of 3MM screws, there should be plenty of room for hats on top of the pi though mileage may vary. Feel free to ask if you want any changes/modifications to the files.

Changed the file to suit 3mm screw mount for Blinkinlabs' 19cm network rack design.
