Charles To make a miniature elevator, you need to buy a slider that matches this motor. Generally, you need to buy a flange (inner hole 4MM, pitch 0.7MM). It is better to take notes with more than 3 motors. In addition, you need to use a DC power supply, DC6V or DC 12 regulated power supply. Also need to buy a motor speed controller (controllable forward and reverse).
