Use plywood (10 and 4 mm thick) to make the fitting path parts. The maximum length of a path part equals the width of the plate. The width of the path parts has to be at least equal to the sphere diameter. Well suited are e.g. spheres of computer mice. Those are big and heavy.
Caution: You need path parts on the left and on the right! To keep the parts clinging to the plate, glue 3 - 5 cube magnets on the plate.
Loosely bolted aluminum pads and jolting paths add sound.
A well-known Swedish furniture store as well as various mail-order companies sell drawing paper on rolls. With fasteners of 16 mm plywood and glued-in cube magnets, another function can be added to the ball path.
