How to Make a Compact Animatronic Eye Mechanism with 3D Printing and Arduino

This project is an upgraded version of my previous design, a highly compact and robust animatronic eye mechanism which uses 3D printed components and an Arduino microcontroller. If you are able to get hold of servo ball-links and pushrods, and are reasonably competent with 3D printing, this is the eye mechanism project I'd recommend most!

- Screws: amzn.to/3Vmtrjg (this kit should cover you)
- Around *40** *M2 x 6mm* screws
- *6* 10mm M2* screws
- 6* MG90s servo screws (these come with the servos: amzn.to/33VfIlF)
- Hobby Components
- *4* M2* Servo Ball-links: amzn.to/3TEbz1R
- *4* M2 x 25mm* Pushrod Connectors: amzn.to/3Pl44uc (keep in mind this is just *2mm* threaded bar - you could always cut down a *25mm* bolt or some plain threaded rod)
- Electronics
- Arduino Uno: amzn.to/3VfGbYR (or anything that can accept three analogue signals, one digital and communicate through SDA/SCL ports)Adafruit PCA9685
- 16-Channel Servo Driver: amzn.to/4cijGsg
- 5V Power Supply, around 4A is more than enough: amzn.to/49Wqni0
- A female DC power jack to match your power supply, to be soldered to the servo driver board: amzn.to/43j0KFC
- *2* axis Joystick: amzn.to/2NR4JnY
- Potentiometer (optional): amzn.to/2r0nADS
- Push-to-make switch (Some joysticks have this built in, but its easier to control when it’s separate: amzn.to/32Wnvyh )
- 10k Resistor: amzn.to/374seRU
- Jumper cables: amzn.to/2NToCuw
- *6** MG90s servos: amzn.to/4afx4vv

Also, a pin vice hand drill might be useful for adjusting hole sizes: amzn.to/4afx7rb
