Built to connect with Will Cogley's wonderful 3D printed animatronic eyes, which can be found HERE.
More information about my build specifically can be found HERE.
This was created to make display and movement easier for a public open-house event. As such, it heavily used materials already present. A standard 4xAA battery box can be locked into the base with magnetic retaining arms. Arms use 3mm thick 8mm diameter magnets, which are dropped in using the pause print command. A ¼" standard nut can be dropped in the same way to create the embedded tripod mount.
The author remixed this model.
