The designer used two stepper motors in their creation. The maker who linked two eyes mechanically to one stepper motor showcased a similar approach on Thingiverse with the link https://www.thingiverse.com/thing:3199810. This design takes a different tack, using integrated gear wheels to accomplish the same task. It is straightforward to print and assemble, and it's prepared for the up-down movement of the eyes. A video demonstrating its functionality can be seen on YouTube at https://youtu.be/t7YhmrVFsBY.
