Glue in the 18650 battery holder, switch and speaker with your favorite industrial strength adhesive. I used e-6000 for my build. Run the wires in the channel on either side of the battery holder. Use double sided tape to adhere the sound board to the chassis. Battery can be removed by pressing on the back side of the battery through the window in the chassis. Enjoy!
