Hand crank generators are a somewhat old-school but still effective and fun way to generate power. If you're someone who appreciates the output, reliability and rustic charm of an old-school hand crank generator but also happen to have some sort of interest in modern processes such as 3D printing, this particular DIY hand crank generator will make for a truly engaging and rewarding project.
This rugged hand crank generator consists of plastic parts that can easily be created and printed on a Makerbot Replicator and Ultimaker 3D printer. Despite this simple creation process, the generator is capable of an output of 30 Watts of power, thanks to its rotors ability to spin at close to 1,500 revolutions per minute.
Robust, powerful and reliable, this hand crank generator is a rewarding and eco-friendly DIY project.
