Hand-Crank Breeze Fan

This palm-sized, 3-D-printed fan puts a full 100 mm high-flow propeller in your hand, driven by a smooth gear train that packs serious air into every squeeze

 

A built-in free-wheel clutch lets the middle gear disengage the instant you release the trigger, so the blades keep spinning—no more timed pumping or sudden stops

 

Whether you’re fighting a stuffy office afternoon or grabbing a quick breeze on the balcony, this compact gadget brings engineering fun and instant cooling anywhere the sun gets too bold

 

Both PTA and PETG works but PETG is highly recommended for the spring.
