Here’s a look back at several cool hobbyist-level gadgets and a few super cool printed car projects.

The price of 3D printers has become reasonable enough to where hobbyist and businesses can own at least one machine. But once you’ve got it, what do you do with it? Engineers and techies will want to pursue DIY projects, repair machines and equipment, prototype their latest and greatest invention, or just have fun. All of these – but especially the latter – require a STL file and a 3D model. Here’s a very short list of places to get the coolest files for your 3D Printer (and many are free).


One of the biggest content repositories for 3D printer models on the internet is Thingiverse – the site offers close to 2 million STL files. The website is operated by MakerBot Industries, the creators of the Replicator series of 3D printers. The Thingiverse community mostly share their STL files for free in varying categories and complexity.

Need a few gift ideas for the holiday? Try this imaginative bottle opener and cap gun, uploaded by 3Deddy via Thingiverse. Aside from the printed parts, all you’ll need are a set of M3 bolts, an elastic rubber band and a penny or 10 cent eruo coin.
