Fully 3D printed bearingless fidget spinner

This was an experiment to see how well a fidget spinner would work without bearings. To test it and to guarantee success I made sure as little of the two parts were touching each other to limit contact and friction. As a result I quickly found out bearings work better. Especially metal ones. But if you are looking for a fidget spinner that is less complicated and easier to print this is the one for you. Good luck!!! By the way it doesn't spin for more than two seconds which sucks to be honest. Anyways it was a fun experiment.
