Century Hawk

Fidget Spinner. Looks great, but spinning is a bit off due to the lack of radial symmetry. Originally, I created this in two parts - top and bottom - and then glued them together, which worked well with supports. However, I wanted to design one without supports, so I made it as a single piece. I inserted a common 22 mm skateboard bearing, along with six 5/6 hex nuts. Both the bearing and nut openings are designed for an interference fit, requiring some hammering to get them in place. The bearing is greasy, causing it to slide out if used frequently or roughly handled. To improve its retention, you might clean off excess grease from the outside, but I opted for the Simple Bearing Cap from Very Customizable Fidget Spinner, making it easier to grip and keeping fingers grease-free.
