If I’m being perfectly honest, I wouldn’t bother using my files. If you are willing to use more traditional joinery methods for the frame, or construct it differently, it would be a lot more efficient to produce. The frame design I came up with was kind of experimental.
Using box joints or splines would be way easier to get a good fit. Would also be much better if you glued in the mirror at the end, or use tabs to hold the back mirror in, like in a picture frame, so that you could wire up the electronics without being so constrained.
