Well, I finally did up a "rough draft" of what I'm planning.
Here's about what it will look like.
The lines are extra-thick, just so they show up nice for you to see. In the actual layout for the laser, they would be infinitely thin cut-lines.
The logo in the middle will be etched so that the high-lights of it will be white, similar to the plastic "tokens" I posted earlier.
I'm not sure yet exactly how I will embed the LEDs. I suppose that if the case material was thick enough, and the LEDs were skinny, I could drill holes in the edge and poke the LEDs right in there.
By the way, the measurements here aren't exact, so please, nobody say, "hey, that hole has to be one 1/16" to the left!" Because I already know that!
I also just show one round hole for the throttle, 12V power, and pre-charge wires to poke through. I lost my RS232 cable a while back, so I do NOT have a serial port connector cut-out shown on the case.
I originally just put the M-,B+,B- marks on the case just as a note to self, but thinking about it, that would be a really good idea to mark them on the case. I think they should go ABOVE the bus bar holes, to make them easier to read when the controller is mounted.
I also think that I want to power the case LEDs by a separate, dedicated 12V connection to the car's 12V accessory battery, with a small switch under the hood. The only time that I am really going to show off the controller is at car shows and eco-events, where the car will be parked with the main power disconnected.
