Description
This is the third version of my hand-operated mechanical hand fan. As handy and beautiful as the second version, and as functional and easy to turn as the first. With a large input gear, the hand fan can be easily started, and the well-balanced propeller ensures the best momentum. With as few parts as possible and hardly any small components, the gadget can be assembled very easily and quickly. With many details, I have paid attention to high stability and smooth functionality. With a gear ratio of approximately 1:23, the fan provides a gentle breeze with as little effort as possible. However, it still trains hand and hand-eye coordination, as you repeatedly have to press at the right moment when the lever goes back in to start the mechanism. The assembly is shown in this video :Assembly Instructions: and also explained in the images. There might be some friction during the first assembly. After a few turns, the mechanism should loosen up and work very smoothly. I wish you a lot of fun and a nice cooling experience.
