Flysky GT3C transmiter steering wheel adapter

I have modified my GT3C transmiter and I am no longer using original power button. (Power switch wires are common problem for GT3C users).
I have ordered steering wheel for transmiter from Yeah Racing. As expected not a single one could be modified to use on GT3C. So I started CAD and design quick adapter.

-On hub for Yeah Racing is wheel mounted with 4 screws. One hole had to be shared with screw securing adapter to transmission. In my case fifth screw holds thanks to contact with adapter
