Katorlegaz.com, the good folks who hosted the original Blender Model Repository, has released all of the 3D models on their website under a Creative Commons license. From the site:
All of our 3D models are now Creative Commons, and related web pages have been updated to reflect the new licensing. Special thanks to all who donated to cover legal expenses from when we hosted the BMR.
There are a large variety of models under a number of different categories. Who knows? You might just find a model that you need for one of your projects there. It's great to see that despite the legal headaches that they've had to go through, Andrew and Jennifer are still willing to contribute to the community. Big thanks to them!
