This project is a 3D printed mini helicopter powered by solar energy.
A small solar panel powers a mini DC motor, which spins the helicopter rotor when exposed to sunlight or a strong light source.
The project combines 3D printing, basic mechanics, electronics, and renewable energy in a simple and educational design. It is perfect as a STEM project, desk toy, classroom demonstration, or DIY maker project.
All structural parts are 3D printable and designed for easy assembly.
Features
• Solar-powered rotating rotor
• Easy-to-print parts
• Simple assembly
• Educational STEM project
• Fun desk toy and decoration
• Demonstrates basic solar energy and motor principles
