But I drew up the case in SketchUp, so at least I have something for you to look at.

There isn't much face detail, I was more interested in making sure the guts fit, and seeing how small I could make it. It's about 26cm across, or 10 1/4 inches. It might be a little less than that in the end, I didn't have a measurement for the cart connector so I eyeballed it.

Super thin!
It's 2.6cm if I put in 8000mAh worth of juice, 2.02cm if I only put in 4000mAh. The lump on the back is the extra 4 Li-Po cells. It will be rounder and prettier when vacuum formed, but it's hard to draw compound curves, so I didn't.

Everything fits!
This was a fun adventure in learning how to use SketchUp. It's not a perfect program, but I really love it!
Expect real work soon!
