This setup uses a free software called Opentrack and some fairly cheap parts. If you already own an appropriate webcam, I'd guestimate this setup costs around $30.

Materials list:
3D printed Mount (PLA)
USB UV light and some way to mount it
Hi-Vis Gaffer Tape
Velcro Strap or similar


To set up the model in Opentrack
PointTracker settings > Model Tab > Cap Tab

Height = 60mm
Length = 100mm
Center to outside = 80mm

Tweak your camera settings until all it sees are the points
Set the key to Green or whatever works best with your hi-vis color (pink or green tape also work)
Tweak the min and max points as close as possible to prevent false positives from the background

Setup:
I7 7700K @4.9GHz
nVidia 1080
Logitech C310 Webcam
Logitech 3D Pro Joystick
