Free CAD files are great! Whether you are trying to learn CNC, learn CAD, build an assembly or experiment with a new design, being able to find everything from screws to complete products can be a great time saver!
Here are four sites that we use to find free CAD files:
- GrabCAD – the most popular with the largest amount of free cad files. Pro tip: change the software search setting to the program you want (Fusion 360, SolidWorks, Inventor, etc). Remember, Fusion 360 can import just about any CAD file type, including SolidWorks!
- McMaster Carr – One of our favorite suppliers, McMaster offers a significant amount of their products as Solid Models. Pro tip: use a web browser (Firefox, Chrome, etc) to find the part, copy the part number, then import directly in Fusion 360!

- Thingiverse – Files here tend to focus on 3D printing (Thingiverse was founded by MakerBot)
- Fusion 360 Samples!
Many work holding companies also make either 2D or 3D drawings or CAD files available, including companies like Mitee-Bite, Orange Vise, Pierson Workholding, Raptor Workholding and more!
Those looking for automotive files can find them at SEMA Garage – but keep in mind that these are not free and require a membership.
