Greg Zaal creator of HDRIHAVEN.COM has announced the launch of a new site..
https://3dmodelhaven.com will feature free 3d content all made available under a Creative commons Zero license CC0, which means the models can be used by anybody, in any way, commercially or otherwise.
The site will be funded through Patreon.com and has been awarded a $10,000 start up grant
"Epic Games has given us $10k to work on the initial content for 3D Model Haven. This will cover a few months of full time work on the site and the models, as well as allow us to acquire models from other artists to diversify the content and make it worth your attention at launch."
