Moved some stuff around and changed the cooling to flow from top to bottom between the LED's and image discs.  This should keep both of them from melting down.

Generated the matching cooling duct and added the exhaust holes for this change.  

I also decided to switch to making a PCB for the LED's.  I think that will be easier than modifying the existing boards and since I'm blowing across the front of them, I hope I can get away with less copper and no heat sink.  We'll see.

So for modeling, all that I can think of left to do is...

• Cover snaps
• Display bezel (I have yet to pick a display)
• Battery carrier mount/snaps
• Fine tune the control knob design, and maybe make it an encoder.
