OpenRC F1 HXT900 servoarm & Holder

I didn't have a small rod or anything for the steering of my car so I made this servo arm in TinkerCAD. Its for this Servo I bought from Hobbyking: HXT900 Micro Servo 1.6kg / 0.12sec / 9g.

Then the servo wasn't centered enought so I shrank the default servo holder to fit the HXT900 with the arm.
