A good approach for that kind of shape is to start in 2D. The top and the bottom are rounded rectangles, and the "middle" of your box is another one (although with different size, and maybe inclined?).
I just added a cube at the end of the box difference(). The see-through effect is equivalent to the debug modifier (#). I *really* don't like the default pink of that modifier, so I did my own version with this module:
color([0.5, 0.5, 0.5, alpha]) %children();

Thanks again Antonio. Last question, how did you create the cube to see thru
the internal? Nice!
