Clayface
thingiverse
This is a model that I found here, http://tf3dm.com/3d-model/clayface-7963.html#RefLink.Clayface. The model is small, but scaling up works well. The photos of Clayface have a height of 32 mm, so quite small really. I have been working on cleaning it up to for paint, and will post a complete picture when I have free time to do so.
