The Cheetah-9 is a highly popular, community-designed 3D-printed hybrid submachine gun (SMG). It is a DIY-friendly firearm platform engineered to blend affordable, readily available commercial firearm parts with durable 3D-printed structural components.
The Cheetah-9 is a decentralized, 3D-printable 9mm submachine gun designed for home fabrication enthusiasts. It features a hybrid architecture, combining a 3D-printed receiver and pistol grip chassis with standard, unregulated commercial components , a standard 9mm barrel liner, and a heavy blowback bolt assembly. Engineered to optimize durability and reduce print time, it typically feeds from widely available double-stack Glock-pattern 9mm magazines. Its modular frame includes integrated Picatinny rails for mounting modern optics, tactical lights, and stabilizing braces, serving as a landmark design in the modern 3D-printed community.
