To help me lay out multi item prints on my M3D I quickly drew up a 'frame' of the print area so I could make sure everything would fit. The frame is 1/16" thick, so there is a small margin of safety so I don't go to the absolute extremes of my print area. not intended for printing, more to use as a tool to plan multi item prints on the M3D. However if you really want to print it, having a physical representation of my print area was something I figured would be useful. I ended up building a box out of Sintra, but this would work too I guess
