After laying out a Cyberdeck build using a Harbor Freight Apache 2800 all weather case, I found some usability issues. The worse was that the lid, which is now a keyboard tray, and the position of the hinge caused the case to sit at an awkward and unstable angle. So I whipped up some self-levelling feet that I could attach to the fins on the bottom of the case, that would bump down when the lid was opened to orient both the case and the lid in an ideal way for use. When the keyboard/lid is stowed, the feet lever back down to store the case even more vertically than the default nature of the case.
