Whiteboard Compass

A drawing compass for use on a whiteboard using a common dry erase marker. It uses a 5/8" ID flanged bearing from a tractor supply store and a 3/8" diameter wooded dowel. There are also two #4 x 3/4" long wood screws for the pinch block. See video for a description on how it goes together. Some tolerances are a bit tight and the model was tweaked for use on my printer. Results could vary on other printers.
