Grand Inquisitor ear electronics

I am working on my Halloween costume and created this.

It uses a common 5 mm diameter red LED, a 220 ohm resistor, a CR2032 3 V battery, a little wire, and a CR2032 battery holder with on/off switch, which can be bought here: https://www.amazon.com/dp/B0749DS2HN?psc=1&ref=ppx_yo2ov_dt_b_product_details.

I did not even bother to solder the wires--I just wrapped them together and used a hot glue gun to hold everything in place. I connected the resistor to the positive terminal of the battery holder and the long wire of the LED. I connected the short wire of the LED to the negative terminal of the battery connector via a small piece of flexible wire. I thought it turned out good enough to share on Thingiverse. Happy Halloween!
