Pinball Chime Unit

After trying to find a used pinball chime unit online for sale for my virtual pinball machine and failing, I decided to create my own. This is an original design by me. It is designed to be mounted to the edge of 3/4 plywood. A detailed parts list and assembly guide are below.

At any time you get confused as to what part goes where, please refer to the picture where all the parts are labeled for the chime unit.
