I was originally going to have my CPO printed with the buttons marked on the printing (I skipped joystick hole markings for some reason I long ago forgot). Has anyone done this, or would it be better (as I suspect it will be) to just print up my CPO, put it on the CP, and then print at home my button layout template, awl-punch the centers, and then drill the hole right through the CPO?
I'm using a forstner bit to drill the holes, so I'm FAIRLY confident that it won't tear the CPO, but there's always that chance in a million (one in ten, usually in my case

) so does anyone have an idea on how to put something over the CPO to lessen the chance of tearout as well.
Thanks for answers to all these questions.
