This is an exclusively decorative model of a surveillance drone camera gimbal. Why is it so happy? It sees you when you're sleeping, it knows when you're awake. It knows if you've been bad or good, so creep out your conspiracy-theory-loving uncle by printing one of these in a bright color and hanging it on the Xmas tree. Better yet, use this as a photo frame. Cut out a photo and put your uncle's face right there on the gimbal. Ball is 3.6" diameter and is pose-able in the yoke. No provisions have been made internally for this to be made functional or to hold a camera of any kind. There are four different parts, but you will need two copies of the "ring" part for the left and right sides of the ball. You will also need [email protected] #4 screws, about 3/8" long. The paper face is optional, and is about 1.9" in diameter. As shown, I printed it in natural PLA without support.
