Not everyone can be an expert freelance CAD designer, but you don’t have to be to build whole worlds using 3D models. Some websites allow you to download free 3D models that you can use to flesh out game worlds, redesign your home, or use just for fun.
There are a lot of uses for these models, ranging from 3D printing objects you can use in your own home and creating new inventions to trying out the inventions of other people.
Here are 26 free 3D models, mechanical CAD designs, and downloadable inventions from Cad Crowd—and there are hundreds more. We’ve selected some of our favorites, but you can always see more by browsing the hundreds of 3D models and designs available.
