2024-10-01 (Tu) GrinderCompassMKIII Floating magnet

I abandoned the idea of placing a magnet on an axle above a float and guiding the axle even higher. I revised the model so the magnet would go at the bottom of the buoy, and the cylindrical walls would keep it in line with the container. I may use a liquid lubricant between the buoy and the container to cushion the jostling and prevent stalling.
