PROC board mount - SW-16 and PD-16

This part can be used to mount either board under the playfield, one on each side (need 2 towers). If necessary, chop off one of the legs if things are tight. The screws for mounting the pcb's are #4. Use a #8 screw to mount the towers themselves.

Updated to add slots on the bottom to add zip ties for cable management. Credit to Ed Owens for this idea for use on his "ghost in the shell" pinball project.
