First big prop is finally done! Total time to completion was just short of one year. Original model was kindly done by misterchiefcostuming on thingiverse. Curved bits were smoothed over with modeling foam and the ammunition ejector was done custom by me in Google sketchup (it's okay to laugh at that)
I wanted to share these custom dog tags by D3ltaProps on Etsy, he makes awsome halo 3d prints. You have a choice between marine or odst and sparten. They are pretty high quality and I definitely recommend them.
