Yoyo Fidget Spinner

thingiverse

Pull the rope until it starts winding up. Continue that motion until your fingers refuse to cooperate any longer. The central part is wider than the rest and should fit snugly over the ball bearing. The smaller component remains loose within the rotor, which features a printed support structure and an opening for the ball bearing. Removing this support structure is relatively straightforward. To align it with the picture, rotate the X-axis by 180 degrees. The pin secures the structure in place and clamps down on the core. All six nuts are M8 in size. As demonstrated in the video, some practice may be required before achieving a smooth spin.
