LED Headtracker

This is a LED-mount for IR-LEDs to put on your headset.
The LEDs (SFH 485 P) snap right in. In my case at least. The tape you see in the pictures is to hold the cable in place
I power it with a 9V battery, but i guess normal AA batteries give more mAh. Maybe you can fit a holder for them in there.
There is a place for an on/off switch.
I use velcro to hold the battery and the clip in place, but made some holes for zip-ties.
It is designed rather sturdy and thick.

I used the standart OpenTrack measurements.
