So, this may be a stretch... I'm an engineering student and I have a 3D modeling assignment in one of my classes. I want to bust out the big guns and create a scale model of Spartan 117 (this would get me way beyond a 100% since my teacher is a Halo FANATIC... even more than me!). I've started working on it by eye from various pictures and pauses during gameplay... but regardless, its not an easy task. Does anyone know if its possible to obtain the dimensioned specs of Spartan 117's armor??? If so, PLEASE PLEASE let me know. I can rock out a pretty sweet model by eye, but dimensions/sketches/whatever is available would make it WAY easier since it is due in T minus 2 weeks:/ Thanks so much!
