This Arduino project uses an Optical Flow Sensor (ADNS3080) to capture movement.
Then translate the data to move servo's making it look as eyes are following moving object.
2x eyeball - Best to print multi-colore (you can use prusa ColorPrint at: https://blog.prusaprinters.org/color-print/)
Color change I used:
z 0 - white
z 13.9 - black
z 14.1 - blue
z 16.7 - black
eyeball-3c.gcode is the same as eyeball.stl with color change.
Remember to come back and post what you've printed as Make.
It's good for the designer and the community (that means you)!
To post a Make, come back to this Thing and click Post a Make.
Or, you can use the Thingiverse Mobile app found on
and the Apple App Store.
