Hi, I am working on making a custom acrylic case for my extra dolch PCB, and I finished the top part of the case, but I realized the easiest way and most practical way to pull this all off, is by also adding a plate... This is where the troublesome part comes to me. I have no clue on how to make an accurate plate that will work with the PCB, so any help will be appreciated! This is what the top part of the case looks like, and the measurements are all correct!
