I also played around with some more "CAD" - cardboard aided design.
Since I don't have a laser cutter at home, I figured a great way to test things out in the physical world from the virtual one is simply to hit "PRINT".
The humble ink-jet printer is a fast and cheap way to prototype anything 8.5"x11" or smaller!
I printed up the ends of the case and cut them out with a scissors, and cut the bus-bar holes with a sharp knife over a cardboard mat.
The great thing about this is I can instantly see what does and doesn't line up! The paper is also great, because any changes or notes can be written right on there. If the bus-bar holes don't quite line up, I can tear or cut the paper to make it work, and then match that up in my drawing software.
I was also able to see what size hole I really would need for all the wires to poke through.
