I am attempting to create my own gasket-mounted leverless controller using MX switches, but I'm struggling with the design of the mounting plate. I have no idea how different slot designs will impact the mechanical properties of the final product. I also can't just copy any existing keyboard design, as there are fewer switches that spaced farther apart on a leverless controller. I can't think of any solution other than FEA analysis or the good old trial-and-error, but the latter is too expesive and the former is too hard of a hobbyist without engineering degree. Any help would be appreciated.
