ram

It can be used to make a servo driven actuator. Instead of servo you can use a gear motor. There is an opening in the bottom suitable for M3 nut. The nut should be glued there. You also need a Tamiya Threaded Shaft (3mm). Attach the shaft to your servo or gear motor. Then put this ram to the shaft. When u start the moto ram will go up or down according to the motor's turning direction. (for custom size's please don't hesitate to get in touch with me)
