Custom Piece Miniature – M3 submachine gun – 3D Print for LEGO Minifigure

This is an accessory for a Lego-compatible minifigure. The image shows a replica of an M3 submachine gun.

The M3 was an American submachine gun that entered service with the U.S. Army in 1942 and was used through the Korean War and beyond. It was nicknamed the “Grease Gun” due to its resemblance to the mechanic’s tool. Key identifying features often replicated in Lego accessories include its simple, cylindrical receiver, the straight box magazine, the basic pistol grip, and often a representation of the small ejection port and charging handle. This accessory displays these characteristics. The filename “M3冲锋枪” translates to “M3 submachine gun,” and the initial analysis also suggests “brickarms m3,” both confirming this identification.
