Solar Powered Mini Helicopter –Easy 3D Printed Toy

This project is a 3D printed mini helicopter powered by sunlight.

A small solar panel drives a mini DC motor that spins the helicopter rotor when exposed to sunlight. When light reaches the solar panel, it generates electricity and powers the motor, creating a simple and fascinating mechanical motion.

This project combines 3D printing, basic mechanics, and solar energy in a fun and educational way. It can be used as a desk toy, educational demonstration, or STEM learning project.

All structural parts are 3D printable and designed for simple and easy assembly.
