I love the fat ring spinning top! And wanted to take it a step farther and faster. I modified by cupping out, the fat ring base so that a standard BB gun BB could be glued in the tip offering less resistance and longer wearability.Next I modified the top spindle to couple to the hand pull, top launcher. WOW!!! Success with over 5 minute spins! Enjoy the best of both worlds!!!
Print 100% fill on the ring for high mechanical inertia and long spin time.
