GrabCAD - over 100k models to download

We posted a couple of years back about the launch of the GrabCAD community, where you can share and download models of everything from cars to gears, and animals to aliens.  Their library now holds over 100k+  models in total across various CAD formats.

While not everything is useful for engineering, there are still some good reasons to use the community.
You can:

• View the model browser of a part you need to design and get tips on methods and technique 
• Supplement an animation with extra background models (remember to give credit)
• Test out your new 3D printer with something quick and easy
• Use test geometry to run through your simulation package
• Test the import functionality of your CAD application by downloading non-native models
