This is a 3D printable, compact, break-action single-shot Derringer chambered in .22LR. Inspired by classic pocket pistol ergonomics and optimized for modern additive manufacturing, this design features simplified mechanical components to ensure smooth operation and easy assembly.
The model relies on standard hardware alongside printed components, utilizing a robust hinge mechanism and manual trigger system. It is designed specifically for high-strength filaments to withstand structural mechanical stress during assembly or handling.
Hardware & Print Requirements
- Material: PLA+ or Carbon Fiber Nylon recommended for enhanced durability
- Infill: 99% infill for high-stress parts (breech, frame components); 15–20% for cosmetic grips
- Walls: Minimum 6 walls for structural integrity
- Supports: Print-orientation optimized; minimal supports required
- Required Hardware: Standard M3 screws, nuts, a tension spring, and a compatible steel barrel liner/insert
