Celtic Skull Necklace

I decided to make the hollow Celtic Skull into a LED necklace! I also did a single-skull version by gluing in some glass eyes purchased on Aliexpress. I created a flat spot inside to which you can glue an 18650 battery holder. Some self-flashing LEDs and a small slide switch are the parts I used for the 5-skull necklace.
You can change the model (remove the support bases if you want) by editing [the model on Tinkercad](https://www.tinkercad.com/things/j6ezDX5jyNj-halloween-led-eyes-skull)
