This looks stellar. great job so far! I tried to make a clay master recently and it was a colossal failure but this definitely gives me hope. I know it may be too early to bring this up, but I have an idea for the eyes. after reading Sylgian's war hammer space marine build, (http://www.therpf.com/f24/sylgians-40k-space-marine-completed-179602/index6.html) perhaps blue "glospex"may work for the eyes. Just a thought. Best of luck,
yes I made the file myself. For 3d printing and pepakura.
here is the pepakura file: http://www.405th.com/half-life/download-761-metrocop-helmet.html
Hey! Do you still have that pepakura file laying around somewhere? I've started a metrocop cosplay build and found this thread, I'd love to use your model
