Design Concept
This toy fan draws its design inspiration from simple mechanical engineering principles and uses a colorful array of components to enhance its appeal to children.

Functions
It is intended as an educational toy that helps children understand basic mechanical operations, develop hand–eye coordination, and explore the relationship between gears and motion.

Printing Recommendations
It is recommended to use PLA filament for safe and easy printing. Print each component separately, and ensure that all parts are securely bonded during assembly.

Assembly Instructions
Align each gear and propeller with its corresponding shaft, then secure them using the included pins and connectors. Make sure the crank handle is installed correctly to ensure smooth operation; if any parts feel loose, apply a small amount of glue.
