Description
Previous handheld fans, while providing coolness, caused hand fatigue.
I've created a handheld fan that uses a spring mechanism for extended rotation with minimal effort.
A few turns with your index finger provides prolonged operation.
Inspired by a double-scoop ice cream cone, its appearance also evokes a refreshing feeling.
This model features a mint chocolate color scheme.
Caution: Staring at the gear mechanism may induce a hypnotic state.
This design requires only 3D printing; no additional parts are needed.
The base is secured by inserting a 1.75mm filament.
PLA may be prone to breakage; PETG printing is recommended.
Two springs are included: a standard spring and a thicker, stronger spring.
Begin with the stronger spring.
Once lubricated and rotation is smooth, switch to the standard spring.
The stronger spring offers more power but shorter operation; the standard spring provides less power but longer operation.
To improve airflow, I've uploaded the fan blade STEP file separately.
Seeking remixes to optimize airflow—suggestions are welcome.
Addendum
Profiles with 6 and 8 blades have been added.
