Reasonably screen accurate rebel pilot comm pad from Star Wars a New hope. Its been designed to print on an angle to maximise the resolution for the holes and details on the compad, but I have supplied the sketchup file I used to create it in case you need to change it. It would also work as a Tie pilot comm pad if you changed the colour.
I have added a slightly newer version which has a hollowed out cavity at the rear so one can add electronics. It also prints more square.
