Dummy 13 Battery backpack

I'm playing around with ways to power dummy 13 without too much complexity. Here's the first try. The backpack fits a CR2450 perfectly and you can easily pull the battery out. This way you don't need a switch. I modified the dummy head to fit a tiny 3 volt LED. Simply glue the wires to the inside of the battery backpack and you're all done. Let me know if you have any cool suggestions to power dummy13. Shopping list: CR2450 battery. You can buy those anywhere 3 Volt SMD LED: https://aliexpress.com/item/1005006589839325.html
