Anim8or Community

It all depends on what you want to use it for Joseph. You also have other formats like 3DS and the many other 3rd party model exporters. Plus you'll need a utility to view the model outside of Anim8or. I use an old  free one called Discreet's 3D Exploration to both view and convert models to other formats.  

At the top bar, do this:
Object => Export... => Save as type: Wavefront (*.obj) =>
you probably know what to do after that.
