Fan Blade

thingiverse

A fan's whirling arm spins round and round, slicing through the air with a soft whooshing sound. The curved shape of its leading edge cuts through the breeze, creating a vortex that pulls in surrounding air and propels it outward with a gentle force. As it rotates, the fan blade creates a soothing melody that fills the room, a calming presence that quiets the mind and lifts the spirits.
