Physics Rotation Pulley

This project turns a MakerBot filament spool into a physics rotation pulley. The pulley is designed to be used in physics classrooms to showcase concepts such as rotational inertia and simple pulley systems with weights. The large size of the spool/pulley makes it ideal for these labs as it is "massive" and has a larger radius than the typical physics pulley. It is a cheaper alternative compared to purchasing large pulleys (example: a Bicycle wheel) and it also reuses empty filament spools.

The 3D printed clamps are designed to fit over the outside of the MakerBot spool and clamp into the notched sections in the center. The clamps hug the outside of the wheel and bridge the gap between the two edges. Although it is a little difficult to put on (it requires a little bit of bending), the clamps should fit securely. In order to save material, a notch was cut into the flat sides of the clamps.

The Sector Bridges bridge the gap in between the Sector Clamps. These were created to help
