RC controller steering wheel reducer(?)

Simple steering wheel transmission, which increase the steer angle 2,5x.
Designed for the car RC transmitter (surface transmitter) https://www.thingiverse.com/thing:3819938
First impress is good, concept looks promising.
Still in progress...

I hope the ssembly is easy, steering wheel position is adjustable and should be fixed by some screw or by the hot glue.
