Fidget Spinner Plug

thingiverse

This creation was crafted with Tinkercad to fill the gap on a typical fidget spinner, which is usually held by a 608zz bearing. The interior hexagonal space was engineered specifically for a 3/8" nut to be securely press-fitted. Using a bearing solely for added weight when a nut accomplishes the task just as effectively at a fraction of the expense seems unnecessary.
