I think I figured out a way to secure the wires to the hinged fuse panel that doesn't stretch the wires. Just wanted to post it on here for other thoughts/ideas.
1st pic, the ruler shows the unsupported 9 inch section that allows the bend. It is 8 awg and will be joined with 6 or 7 other wires. The other wires from the fuses would have to be run parallel in separate runs.

Second pic is underneath/backside of fuse panel in the fold down position. The adel is bolted to and rotates with the fuse tray.

Third pic is the top/front side of the fuse tray with the 8awg sticking through a plastic snap bushing. The other parallel wiring runs would have other snap bushings.
