3D printers are becoming increasingly popular, as more and more people warm up to and adopt the concept of 3D printing. One great example is Kickstarter’s project, The Micro, which was developed for a 3D printer for consumers. It was funded in just minutes. However, you just can’t start printing right away once you get your 3D printer. First, you’ll need to get the necessary materials and more importantly, the blueprint to print out your product.

Sounds difficult, right? But don’t worry, because the Web is now filled with sites that offer users free 3D models to print on their printers – completely free of charge! And in today’s post, we’re going to highlight 10 such sites that you can use to search and download free STL models for 3D printers. We hope you’ll be able to find what you’re looking for in these spots.

Enjoy!
