STLanon, here's something at least in case you haven't found a model yet. It's FBX because I wanted to include a basic skeleton for posing, and you'll have a better idea which STL settings to use for it than I do anyway. I've never done anything for 3D printing so I have no idea about the limitations and would be surprised if this works first try, so let me know which parts need to be fixed or changed and I'll try to get them done
