I was expecting a big mess of polygons spewed out of 3DS Max, but I can actually see how this came out of my model, though this is still looking a bit rough for the laser cutter, so if I choose to use the stacking method I'll have to clean it up a bit. But for now this will do to cut out into paper or cardboard to test whether it is a viable endeavour to improve this stacking file or find another method of assembly
