For when I get hangry and need a little boost, this is my 3D printed ration case. It fits well in pockets and has a long shelf life.

Yes, carrying a protein bar or nature Valley bar would accomplish the same thing. I just made this for fun. The 3D printed box ensures that it doesn’t get squashed in your pocket. 200 calories isn’t a lot but in a pinch it helps relieve hunger symptoms.
