Hey Paul,
Sorry that's my fault, I printed the pdf without reversing the layout. It is printed so you can overlay the top over the bottom and the holes will line up. It's easier to check it that way. To etch the board I would have printed it in reverse.
Have you thought about using connectors between the 2 boards instead of wiring? It would make the whole assembly a bit easier. It looks like you are using tapped spacers to hold the boards together, so connectors could be the way to go.
