Took forever to get around to this, but finally got a chance to make a rough prototype. Concept on this one was to have a pouch that can hold a DSLR camera and be able to go from secure to in hand as quick as possible. It ended up being pretty honkn' big, but was the size needed to cover the camera and have the 45 degree extraction. The inside is Tricot foam so I can make velcro dividers and holders commonly seen in camera bags.
Currently I am just using 1 as seen in last pic. Pockets include simple slim one on top and zipper pouch on the front. An extra opening is on the lower side to access space that is created from the 45 degree placement (as seen on pic5). If I get around to making another one I'll finish up the zipper and binding up propper. Functionality wise it works overall well, but I would make the main opening zippers longer for easier extraction.
