Enclosure for Running Belt Electronics

Instead of screw supports, have you entertained mounting components to a board that slides into extrusion and is held in place by 3D printed endcaps? Could hold the whole thing together with a single screw, and body strength wouldn't be an issue at all. I didn't get a chance to look at the prototype you brought in, so it really depends on how you plan on mounting it.
