Difficulty & Build Time
- Skill Level: Beginner
- Estimated Build Time: 4-6 hours
- Required Experience: Basic knowledge of 3D printing and assembly; no prior firearm-building experience necessary
Hardware and Tools Required
Required Hardware
- 8 M3x20mm button head screws
- 6 M3 nuts
- 1 10mm OD x 1mm wire x 50mm long spring (or 8mm/3/8” OD with 1mm wire minimum)
- 1 Rifled .22 barrel liner, 37mm long (or 9/32 OD x .028" wall x 37mm long steel tube)
Recommended Tools
- Driver for M3 screws (hex, Phillips, or flathead screwdriver)
- 5/16 drill for .3125" OD rifled liner (or 9/32 drill for steel tube)
- #1 drill to chamber rifled liner
- Super glue or epoxy for securing the barrel liner
- Clamp, vise, or hammer with a wood block for pressing components
The Harlot Parts
The Harlot file includes all necessary STL components to print and assemble this compact .22LR pistol. For optimal results, we recommend printing with a high-strength material like PETG or ABS to ensure durability under stress. Pay attention to layer adhesion and use a minimum of 50% infill for critical parts to maintain structural integrity.
First-time builders should follow the detailed PDF guide linked in the Read Me file for step-by-step instructions. Special care should be taken when aligning and securing the barrel liner to ensure safety and functionality. Stay tuned for upcoming variants, mods, and stipple packs to customize your Harlot build!
Printer Compatibility & Settings
The Harlot design is compatible with most FDM 3D printers, including popular models like the Ender 3, Prusa i3, and similar desktop printers. For best results, use PETG or ABS materials to balance strength and flexibility, as PLA may not withstand the mechanical stress of firearm components. Recommended print settings include a layer height of 0.2mm, a nozzle temperature of 230-250°C for PETG (or 240-260°C for ABS), and a bed temperature of 80-100°C.
Ensure proper cooling and ventilation when printing with ABS due to fumes. A minimum of 4-6 perimeter walls and 50-70% infill is advised for durability. Always double-check your printer’s calibration to avoid dimensional inaccuracies in critical components.
Conclusion
The Harlot is the ultimate choice for 3D printing and firearms enthusiasts seeking a simple, strong, and reliable .22LR pistol build. With its beginner-friendly design, minimal hardware requirements, and detailed instructions, this project empowers builders everywhere to create a functional firearm safely.
