Dynamics cart end caps

These cart ends are designed to replace the caps on the ends of metal dynamics carts used in physics lab.  There are versions for both Pasco and Vernier carts, with plunger and standard ends for both.  The caps are designed to work with the tab system used in Vernier's Go Direct carts, allowing for quick swapping of velcro and magnetic ends.  I have include models that have the tab slots inverted and upright.  The inverted ends allow for swapping of tabs from above, while the upright ends require swapping from below, but are also compatible with the Eddy Current Brake and Friction pad sold by Vernier.  I have also include a file for the tabs.  The tabs are designed to work with ½" diameter by ¼" thick neodymium magnets and ½" hook and loop dots.

The pasco plunger cart ends require some assembly.  You will need to super glue the rectangular prisms to the back of the end caps in the slots. This is what holds the plunger lock mechanism in place.

The Vernier Plunger cart end on the plunger side is a bit tricky to replace.
