I took his model that I purchased from etsy and retopologized the entire outside main shell so it could be around 1/8" thick throughout the whole helmet, adjusted the bands under the helmet to be less pronounced, re-did the trim around the helmet, imported and curved all the etchings and attached all the greeblies to the model for printing. I sent him an updated zbrush model if he wanted to do anything with it, but as far as I'm concerned, my tweaked model isn't mine to give or sell away because it's all based off his work. The cost of the print was around $350 but shipping was just as much as the print itself. To get a paint ready print of this for under $800 seemed worth it to me
