trackir pro no clip / headphones. (no supports print)

I was looking for a trackir pro that did not need headphones. could not find one so I made my own. Design should work for TrackIR as well as OpenTrack etc software.

Parts needed:
3pcs IR LEDs
1pcs resitor (or if you can't match the exact value combine two in parallel)
4pcs thin wires (I used 26 AWG).
1pcs thin steel wire ~20cm (to pull 2 wires threw diadeem.stl part)
1pcs battery holder (2x aaa)

to help you find the resitor value with the ir leds
