Caliber: 5.7x28mm
Bullet Dimensions: Approximately 5.7 mm diameter by 28 mm length (case length), designed for compact personal defense weapons.
3D Printing and Models
- Note on Printing: Full functional firearm receivers typically require strict adherence to local laws, and standard desktop 3D printers have build volumes too small to print a full-size rifle frame in one piece, requiring split parts.
- Receiver & Shell Assembly: The frame is split horizontally or vertically into several large segments. This layout allows it to fit onto standard desktop 3D printer beds (like a 220x220mm build volume).
Material Requirements: Builders heavily recommend high-strength materials like PLA+, PETG, or Carbon Fiber-reinforced Nylon to handle the mechanical stresses, impact forces, and heat generated by the action. - Not provide, including pins, springs, a metal barrel liner, and a bolt assembly, to function safely
