If you are interested in owning a lorica segmentata in some form other than a full-sized replica, there are a couple of possibilities.
First, make a card model. Download a PDF (you will need Acrobat Reader in order to view it) containing the images you need, print it out onto a stiff paper or thin card using a colour printer, cut, fold, and glue as instructed on each sheet.
Still too messy and too much like hard work? Then keep your reconstruction completely digital by downloading a 3D model or an animated flyby of one.
