I’ve added a second freebie to my Stuff for free page, here on this blog. It’s a cute retro three-wheeler car, an .OBJ conversion of a public domain CC0 Blender model. The original was nice, but had no material zones. I’ve added these, and now you can easily drag-and-drop new materials. Commercial use of your renders is fine by me.
