I need 3d model of Hostile Environment Suit kit is basically just the chest, head and backpack for 3d print. I only need torso, head and backpack with tubing. Check the attachment image name - I need with this backpack. NO need to make hands legs we will attach that only need torso, head, tubing and the mask and with backpack as shown in the attachment check backpack attachment image thanks. I also have two STL model ready in that you can have the helmet and the Chest STL files so if you use that files then you will only need to make the backpack and tubing and the mask if not then make new one if you like. Note : I need STL file at last for 3d printing and i will have continue work for the right candidate Happy Bidding!
