Fully 3D Printable Fidget Spinner

I've seen so many people with these fidget spinners, so I decided to make one that you don't need bearings for.

Obviously this won't spin for very long, you can add lubricant and sand the parts that touch to make it spin longer. I've managed to spin mine for around 10 seconds.

If there is anything I need to change feel free to leave a comment.
