Physics Pulley Holder

I designed this pulley holder to attach a pulley to a table. I also made a force table in order to have students practice balancing forces at different angles. You will need some quarter inch hardware in order to make this work.1 - 1/4 inch 20 threads per inch hex nut1 - 1 ½ inch ¼-20 inch hex bolt for attaching to table.1 - ½ inch ¼ -20 inch hex bolt for attaching pulley to clamp.Consider downloading and using my quarter inch bolt handle, to give more grip on the hex bolt. I have two designs, one has the original model as pictured, while the second has a model I made after measuring the pulley to be 22 mm wide, so it is intended to hold the pulley at the proper angle.
