I haven't been following this thread, but I hope you're not planning on cutting it out in one piece and bending it into the 3D shape you are showing, because it will be impossible on a brake press (if you think about the order of the bending, and what interferences there will be from previous bends, you'll figure out why). I'd look at changing the pattern to make the pattern to cut 2 pieces that get bent into u-shapes and then attached. You'll need to think about adding some flanges (for joining the 2 "halves") onto both pieces, too.
