Anti gravity device

You've never seen a wheel roll uphill, defying gravity's rules? Just watch this incredible desktop gadget in action. A small neodymium ring magnet (10mm diameter, 5mm thick) is drawn to ten tiny (5x5x5mm) cubes, cleverly hidden beneath a track. Before you begin, make sure the cubes are positioned correctly. Simply grasp the ring magnet between your fingers and touch it to one cube. The cube will self-adjust and can be slid into its slot with the ring magnet's help. Repeat this process for each of the nine remaining cubes without adjusting the orientation of the ring magnet or the track. The track's incline is approximately 20 degrees. If the ring stops halfway, there's a good chance the space between it and the cubes is too small. Ideally, you should leave about 4mm of clearance between the ring and the cubes. Now that everything is set, place the ring magnet at the bottom of the track and release it. To your amazement, it will climb uphill all the way to the top. Suppose we could shoot the ring magnet past the final cube and let it roll back down to the starting position under gravity's influence. Wouldn't that be a perfect perpetuum mobile? Unfortunately, there's an equilibrium law at play.

The track is attached to the base at a 20-degree angle. Depending on your printer, you may find that the square holes are too snug. If so, simply scale up slightly to ensure they fit comfortably.
