Wireless Headtracker
thingiverse
In my case I used code by Cliff from https://github.com/dlktdr/HeadTracker. Settings are D3 for reset center The design is based off https://www.thingiverse.com/thing:4744102 by ysoldak who also did original wireless code. To create the LED ports, I used 4mm lengths or 1.75mm filament. 1 self tapping screw is designed to hold 3.5mm power cable in place, test for shorts before powering on. Omron style 6x6mm tactile switch is designed to fit in without need for soldering. Just power needs to be soldered onto nano.
