There is no better way to get started as a maker than building your own things and 3D printing their components. Baby Bastion is an animatronic puppet you can build with 3D printed components. This Overwatch inspired robot was built using 5 micro servos, RC controller, and a few other simple parts.
The robot expresses its personally through head, body, and eye movements. JON-A-TRON has shared a guide that shows you how to build this robot.
