Bluetooth for Sixth-Scale Action Figures

I'm quite pleased with this, my very first successful "from scratch" model. It's inspired by a piece made by the now-defunct Triad Toys for their original character "Tyrus Kilemahl" (get it?) Tyrus had a nice little bluetooth, and, seeing as in real life I'm almost never without a bluetooth, I bought a few for my "Mini-Me," a 1:6 action figure of myself. But they're tiny and easily lost, and replacements on the secondary market are getting more and more expensive, so I decided to roll my own. I did base it by eyeball and very rough ruler-based measurement on Tyrus' bluetooth, but I built it in Microsoft 3D Builder from scratch, from basic shapes.
