Are there any electronics in the AirPod case lid?

For reasons I won't go into, I wish the AirPod case lid was not so form fitting around the tops of the AirPods. If I knew there were no electronics of import in the lid itself, I could make the changes I desire with a Dremel tool. I watched the teardown video but removing the lid lining was not performed. I'm hoping the lid is free of electronics and that the hinge connection is all that is going on there.
