Non "t-pose" 3D models

[Treethrower]

I've seen some 3D models pulled from the dev kit up on Thingiverse. But they all seem to be in a standard pose. Not quite a T-Pose, but somewhat equivalent.  

 

Is there any way to pull a model of,  for example,  an Argentavis stalking? I like that pose, and would love to 3d print it for myself. 

 

Thanks.
