It's definitely a fad, they rose along with the 'fidget cube' from the EDC (every day carry) community. I found these over a year ago on Thingiverse. Since then I've made ~$400 selling 3D printed frames to the local skate shop (because they have the bearings).
Once the kids heard about it, the spinners flew off the shelves. They were also popular with people who have ADHD and those in rehab, giving them something to do with their hands.
When my printer broke a month ago they didn't wait for me to fix it and bought their own. They now have an order of over 200 units and nobody that knows CAD design... guess who they called for help.
