Lift Heavy Objects Using SCIENCE & 3D Printed GEARS!

Gearboxes are always amazing. You can lift tons of loads with them. In this video i made a 3d printed gearbox and showed advantages of them and for that i used 3d printed PLA herringbone gears. Finally that little dc motor lifts 58kg/128 lb at 125:1 gear ratio(reduction). STL: :4922127 Source Files:
