Inspired by Warhammer 40K, this chainsword building set faithfully recreates the iconic weapon of the Space Marines at an epic 85cm length. With over 1,700 micro-sized pieces, it features a motorized chain function that roars to life, mimicking the thunder of the battlefield as the teeth spin. Designer Dong Dong spent months refining the structure, balancing a solid grip with lightweight engineering. Adult fans can wield it one-handed—an engineering challenge that doubles as a tribute to the aesthetics of mechanical power. From IP passion to mass production, every brick is a salute to sci-fi design.
