The servo attachment (top picture), the 3d box (middle picture), and the gears (bottom picture) have finished printing. Design flaws were discovered during assembly. The servo platform doesn't support the servos as expected. The servo platform sags and creates drag for the servos.

We are converting the potentiometer to wireless.
