A Cute Little Elephant I made. It's a simple model with nice clean geometry and fully rigged. I made this to be 3d-printed so I haven't tested the rig for animation purposes, only for posing.
This file includes:
> The model of the Elephant
> A rig (IK constraints added)
> a wireframe material for cycles + a defuse grey.
It's free to use for anything you want (including commercial use ) as long as you give credit.
