I've included the gerber file for ordering your own LED PCB. This is modeled to hold a 1000mah battery and a D1 mini ESP32.
I haven't really documented making everything fit but use small cables. There isn't enough room for a speaker, so I made a hip box that holds a speaker that communicates to this over bluetooth. I can add the hip box if anyone is interested.
Thanks to hydrate_or_diedrate for the model. I've modified it quite a bit. (if you need to use their model I scaled it to 120%)
The author remixed this model.
