**Possible Uses:** The part could connect many different parts to one main location. It can connect to different types of apparatuses. It can work in various ways, depending on the situation. The knob wheel can change the direction of the movement by about 90 degrees. It can connect to the motor module to also change the direction. It is up to the person building the structure to decide how it should connect and function to carry out the task at hand.
