Here is a guy I made in MakeHuman and edited in Blender. He came out quite well and I only had to do minimal changes in blender for the pose. Just adjusted his hands a bit so that they would be flat against his leg and sides. Of course, as usual, you have to edit the head mesh to remove the eye sockets and mouth but using the hide and then ‘select loop’ tool it’s actually pretty quick.
I have zipped up the final OBJ file (obj was a bit smaller than an STL) and uploaded it here: http://martinsant.net/new3d/
This mesh has been tweaked and run through netfabb to remove any holes or openings in the pants and sleeves, etc. I am not sure of the exact scale of the object but I just resize in Cura before I print it. For 1/29 GScale, he is 60mm tall which comes out to about 5 feet 11 inches or so.
