Robotic Pen Retractor

This versatile servo mount and pen holder empowers students to transform their OneBot from PAtton Robotics into a dynamic drawing machine. The Servo holder and Battery support are both printed with precision adjustment slots, enabling effortless fine-tuning during mounting. To accommodate the pens' movement, servos must be shifted 1/4 inch outward on each side. I employed straightforward 1/4 inch #6 spacers for each of the 4 servo mounts to achieve smooth alignment.
