blendfile.com as a place to share about "Free CC0 3D Models .Blend File".
July 2018 thought to put it online all the assets learned from Blender software, rather than just stored in notebook hard drive. Maybe some people there need it. But that does not mean a reason to learn and become a professional 3d assets, although not every day upload. You may be wondering: why would people spend hours of their own time to create file, share package it, and then give it all away? The answers are as varied as the people who contribute. Some people like to help others.
