Gears and pulleys are the reason TeacherGeek was created. Before Teachergeek, gears were too expensive, too small, or had to be hot glued to shafts to make them work.
TeacherGeek Gears have a spline that allows them to push onto and rotate with a dowel shaft. They can be easily removed or changed for design revision and experimentation, yet they transfer impressive amounts of power.
