Servo Working

I made a project using 20kg Servo, but now I need to reuse the servo. If I were to not have servo the project would be unusable, so I added fake 3D printed ones so that it can keep its structure, and still move if you turn the servo. They have little nubs at the bottom to make it so that they don't rotate infinitely, so they can hold a bit of weight, like the real 20kg servo.
