Bolt Halo Fidget Spinner - Wingnut2k #6

myminifactory

I came up with a fresh style of spinner that I hadn't seen on this site before. Three screws securely hold the center ring in place. This design uses three 1/4-inch nuts, three 1/4-by-1-inch screws, and one 608 bearing. This design is slightly thicker and heavier than your average spinner, but it's still easy to handle. The center ring stands at 9mm tall (the ball bearing is 7mm). The ring features three recessed areas where the screws can fit snugly and help keep the center ring in place. The outer piece measures 11.5mm thick, designed so that screw heads won't protrude too far. This spinner has a diameter of about 3 inches. It's divided into two pieces, allowing you to print the center ring in a different color if you prefer. I've also uploaded models using #10 screws instead of the 1/4-inch screws, resulting in an overall thickness of 9mm.
