Battery mod for FlySky i6

This is a remix from Tavero´s [Rechargeable battery mod for Flysky i6 transmitter](https://www.thingiverse.com/thing:2318788)

I wanted to adapt this mod for use with some 9v rechargeable batteries I had at home.
To do this I redesigned the part to handle a switch and used the following hardware components:

- Buck converter [LM2596](https://www.amazon.es/DollaTek-LM2596S-ADJ-Potencia-regulador-Ajustable/dp/B07DJX97MS/ref=sr_1_2_sspa?sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1) to adapt voltage
- [10x15mm Switch](https://www.amazon.es/Mini-interruptor-rectangular-contactos-SWITCH/dp/B07T9MZD2G)
- 9v Rechargable battery
- [Battery connector](https://www.amazon.es/GTIWUNG-Conector-Bateria-Soporte-Conexi%C3%B3n/dp/B09SG7NYTN/ref=sr_1_15?sr=8-15)
- M3x10 screws for attaching the LM2596

I also had to solder to join the components together and I used hot silicon to glue them to the case.
