And I have finished my ultimate gaming case. The size of a large book, this case is designed to have a space to hold pencils pens and dice, six spaces for miniatures or other widgets (such as Lifecounters - https://www.thingiverse.com/thing:2790840 was specifically designed to fit in these slots), a built in dice tower, and even a slot sized for most tablets!
The third image is a rough diagram of assembly, which I used epoxy to accomplish. In the case of the hinges, I used finishing nails as a cotter pin, and then applied a dab of glue on the pointed end to secure it in place while retaining mobility.
Be warned, this is intended for large format printers such as the CR-10 (and variants) or the TEVO Tornado. I cannot guarantee any structural integrity of this case if shrunken down to fit other, smaller printers.
