I did not make the model itself. I found an amazing ODST Helmet on myminifactory but couldn't fit it on my tevo tarantula large build plate, so I sliced it up into 8 different segments. You will need some supports, and you will need some kind of adhesive to hold it together. You'll probably want to sand it as well.
