I can help you with a suit of armor for a cheap price because financial costs so normal it is around 800 dollars for someone to request a suit but the cheapest I can go is 600+shipping or you can pay in set like the helmet for $60 and left arm armor piece for $100. Either way it will take about 6-8 months to 3D printed a full suit of armor. I will suggest to start with the helmet first then move on from that. Are you doing Marines, ODST, or Spartan
