Warframe 3D models? Obj files?

[//KROENEN\\]

Hello! I'd like to ask where I can get some 3d models of Corpus or Grineer Weapons or Enemies, I would like to try to 3D Print something! the idea of 3D Printing a Corpus Dera or Grineer Grakata to 1:1 Scale would be awesome! or (considering I have one of the larger 3D Printers, a CR10s5 to be exact) I would love to print a life sized MOA or an Osprey to display in all it's glory!
thanks!
