A 3D-printable, hand-cranked generator has been created to inspire kids to think creatively about what is possible. This design revolves around a 12-volt DC motor from a window flusher fluid pump and features gearing approximately 1:29.16. The motor mount was designed for motors with round bodies, featuring an outside diameter of 27.6 mm and two M2.5 mounting holes spaced 16 mm apart. The motor shaft has a diameter of 2.3 mm. The mount can be modified to accommodate various motors.
