sure, feel free to use them but don't sell them please, that's all I ask.
iron man elbow pod.obj
iron man hip pod.obj
Not sure how clean are the meshes, it was ok in blender but I haven't checked them after the .obj conversion. Does the job once printed from the .obj file, but you probably will have to scale them, I do it directly on sculpteo.com, not in the 3D software so if the website you want to use doesn't offer scaling, you'll have to do it yourself.
Here are the pics sculpteo sent me yesterday after they printed everything, I should have them tomorrow
