I was retrofitting a Savi's lightsaber and couldn't find a chassis that met my requirements. Specifically a good fit (diameter, no play) and support for Proffie v2.2, speaker, 18650 battery w/holder, and a rotary connector. Both the chassis and pin side rotary PCB adapter are included. Remove the original internal bottom chassis. The PCB adapter fits in the bottom of the middle chassis that holds the Kyber crystal. Reassemble the original gray bottom shell to the middle gray chassis. Drill pilot holes into the PCB adapter and use the original screws that attached the bottom shell to the middle chassis. Feel free to send me any questions and if you end up using this, leave a comment.
