How to Build a Simple 3D Printed Arduino Animatronic Eye Mechanism

Here's how I build my simplified 3D printed arduino animatronic eye mechanism. This is a good option if you'd like to try out some DIY arduino robotics but don't necessarily have access to certain specialist hobby components, high-quality 3D printing or workshop tools. If you need more help, check the thorough text instructions on instructables:

Parts and Materials needed for this project:
3D Printer Filament: PLA is fine although I'd recommend you use a good brand because some parts are quite small and fragile. ABS is good for making realistic eyes but not necessary.
- 6x SG90 Micro Servos: https://amzn.to/3TEXjpR
- Various M2 and M3 screws although any screws roughly that size should work ok. A kit like this: https://amzn.to/2JOafVQ should cover you.
- Arduino: This design was tested using a genuine Uno, but it's likely that any board which has SDA/SCL pins, 3 analogue inputs and a digital input will work. Arduino Uno: https://amzn.to/2JTs1Hs
- 16-Channel Servo Driver: https://amzn.to/4cijGsg
- 5V Power Supply, around 4A is more than enough: https://amzn.to/49Wqni0
- A female DC power jack to match your power supply, to be soldered to the servo driver board: https://amzn.to/43j0KFC
- *2* axis Joystick: https://amzn.to/2NR4JnY
- Potentiometer (optional): https://amzn.to/2r0nADS
- Push-to-make switch (Some joysticks have this built in, but its easier to control when it’s separate: https://amzn.to/32Wnvyh )
- 10k Resistor: https://amzn.to/374seRU
- Jumper cables: https://amzn.to/2NToCuw
- *6** MG90s servos: https://amzn.to/4afx4vv
Also, a pin vice hand drill might be useful for adjusting hole sizes: https://amzn.to/4afx7rb
