Mint Box Audio Selector: 3.5mm audio switch

Step 2: Prepare the container

Position and size up where you need to make holes for your switch and audio jacks. I use a knife to cut the rectangular holes and after trying to do the same with the first round hole I decided to try a drill press and it worked much better. The lid also needed to be cut to accommodate the parts.

Depending on your materials and preferences location and sizes of the holes will vary. If I do this project over again I would separate the audio holes more as the connectors this close make it hard to reach the wires.
