Pulleys and gears are the reason TeacherGeek was created. Before Teachergeek, pulleys were too expensive, too small, or had to be hot glued to shafts to make them work. 

TeacherGeek Pulleys 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. The unique pulley design allows for non-slip grip and easy exchange of rubber bands.

This 40 Pack contains 10 of the following sizes: 70mm, 55.5mm, 25.5mm, 9mm

Colors Vary.
