Cheap Pulley

thingiverse

We frequently employ pulleys in physics classes as part of lab exercises or demonstrations. However, one major drawback of using pulleys is the significant amount of setup time required beforehand. These basic pulleys can be easily attached to lab tables, whiteboards, and other surfaces using command strips. A skateboard bearing is fitted snugly into the wheel of the pulley and then secured to its base. The bearing necessitates an outer diameter of 22 mm and an inner diameter of 8 mm for proper function.
