Not to thread jack or anything. Make these out of Romark. It's the material used for tactile lettering in signage. Comes in a world of colors and finishes, varying thickness starting at 1/16" and up, comes pre-laminated with 3M vhb tape on the back, and can be cut on an engraver or cnc. Oh and it's also relatively inexpensive (a 2'x4' sheet is usually around $50) .
