If the modification below is made, I think this part can be bent much more easily.

The complete tubes down the sides will still be non-possible with any normal brake (finger or press). If you lose the bottom of the side tubes and have them bend up from the belly pan, it may be possible on a finger brake, and easy on a press brake. Add spacers and dead axles to make up for the loss of stiffness.

Alternatively, take a look at industrial origami. With that you can bend by hand and not have to worry about machine access. I'm not sure how the bends would hold up to fatigue in aluminum, but it might work.
