Mines don't always have to be big, as the American M-14 clearly demonstrates. Small and very dangerous, they can still be found in many crisis areas, especially in South America.
Our 3D-printed M-14, on the other hand, is completely harmless and purely decorative. It looks great on a desk or in an EOD collection.
Of course, it can also be used as a means of demonstration during training to draw attention to the dangers of such a small part using the non-functional dummy.
You'll have to assemble this model yourself. A hot glue gun works best.
