Protecting plastic edges from ball hits

Where the ball clips the edge of a plastic, put a flat fender washer (with a small hole so it cannot shift) under the plastic at its mounting post so it overhangs the plastic edge slightly and takes the hit. Clear plastic deflector washers made for this are kinder to the ball. A piece of plexiglass can serve as a temporary replacement for a missing plastic.
