3D printing and Fidget spinners

The Advantages of rapid prototyping are numerous though I would only like to point out the latest trend on the market that is fidget spinners.

Fidget spinners are all over the place these days, and from a personal experience, I can say that it helps kids calm down a bunch and most importantly help them stay away from phones.

With the help of 3D printing, everyone can invent its own version of the device.
