DIY 16 Channel Servo Tester with 3D Printing and Arduino + Channel Update

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a breadboard and use the serial monitor in the arduino IDE to get the servo positions, but this time I decided I'd treat myself and design an enclosed, permanent system to test my servos!
