Plans include PDF plans with all measurements and a complete SketchUp file. I've also included all the files for the NASA Stencil and the NASA Plaque.
The PDF file can be printed off and has all the information you could need. If you find yourself wanting more information, you can open up the SketchUp Model and get absolutely everything you could want.
SketchUp is free and can be downloaded to view and manipulate the model to give you all the information you could possibly need.
