Fatshark headband and power supply mod

I don't like the side mounted battery on a small goggles, that is why I designed a little hook for a 3 straps headband and a little power supply box with power switch.

The parts what I used:
- Eachine VR006 headband https://www.banggood.com/Eachine-VR006-Elastic-Head-Band-For-FPV-Goggles-p-1185224.html
- 2S balance plug (I cut it from a bad 2S battery)
- 5.5x2.1mm 90 degree DC plug (cut the JST off) https://www.banggood.com/JST-to-DC-Adapter-for-Fatshark-Battery-p-1128902.html
- 2.6V-30V
