So, turns out ramming into the gutter at full speed repeatedly is going to eventually break something

Overview #
My Hosim Q903 RC basher has a small control arm connecting the steering servo to the full steering link. After having it for a relatively short while, I managed to snap the one provided. On further inspection, it turns out this is NOT a replacement part, and instead requires a full replacement of the whole servo component (a Q901-ZJ14).
Rather than purchase a whole new servo, I’ve designed this part which worked a treat! I printed on a Prusa Mini+ in PLA+. I’ve raced the car since and had no issues, even after a few significant accidents. For even more strength. consider printing with ABS I’d suggest.
Hope it comes in handy for someone.
