3D printing is rapidly gaining popularity. More and more available printers appear. But the development of 3D models is still a big problem. Enthusiasts are forced to create them in special editors, which requires some skills and a lot of time, or use the services of paid services. In the framework of the Insert Coin competition of projects conducted by Engadget, inventor John Fehr introduced a software and hardware system that allows you to turn any smartphone running iOS or Android into a 3D scanner. In fact, in addition to a special program for a smartphone, a rotating platform and a laser are included. John claims that the cost of all parts does not exceed $ 300. The author plans to launch his project on Kickstarter soon. I think if the cost of the end device does not exceed the same $ 300, this device can be a worthy alternative to the MakerBot scanner .
