Servo Arms

One of my concerns has been the length of the servo arms to control the eye. Because the eye is larger, I need a larger servo arm to get more of a swing to turn the eye. Servo Arms can get pricey if you need it larger. Lucky for me a friend from work got a 3d printer.   He has been helping with making the arms.  This will be the 6th and 7th try to get the size right. Wish me luck.
