Hummingbird Duo Tray with Zip Tie Slots

This tray is an update of my first effort to secure and protect the Hummingbird Duo boards my students use for robotics. I added two posts inside which better support the uneven underside of the board and keep it level, and I also made grooves and holes so that you can secure the board with zip ties. The power and USB ports are still accessible.
