The Shush Puppy

The Shush Puppy Features

The Shush Puppy stands out as a fully 3D printable suppressor, eliminating the need for pre-made outer tubes or restricted components often required in other designs. Unlike previous monolithic suppressors limited to 22LR or hybrid designs, this system is tailored specifically for 9mm firearms, offering enhanced versatility for DIY enthusiasts.

Key highlights include:

• Modular Design: Allows for easy assembly and customization to suit individual preferences.
• Maintenance-Friendly: Resolves common issues with DIY suppressor upkeep, ensuring long-term usability without regulatory hassles.
• Minimal External Parts: Requires only a muzzle device, reducing costs and complexity.

This design prioritizes accessibility, letting builders focus on creativity without being bogged down by hard-to-source components. It’s a game-changer for anyone passionate about 3D printed firearm accessories.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 12-24 hours
• Required Experience: Basic knowledge of 3D printing and familiarity with firearm components recommended

Hardware and Tools Required

Required Hardware

• Muzzle device (the only firearm part needed for assembly)
• 3D printed components (as per included STL files)

Recommended Tools

• 3D printer with compatible settings for detailed prints
• Calipers for precise measurements during assembly
• Basic hand tools for fitting and finishing
• Cleaning supplies for post-print processing

The Shush Puppy Parts

The Shush Puppy includes a set of STL files for printing all necessary suppressor components, ensuring a fully modular build. These files cover the internal baffles and outer structure, designed to work seamlessly together for optimal performance with 9mm firearms. For best results, use high-strength materials like PETG or ABS to withstand the stresses of use.

Print settings should prioritize detail and durability, with a layer height of 0.2mm or finer recommended for precision. Ensure proper cooling to avoid warping, especially for intricate baffle designs. Post-processing, such as sanding or acetone smoothing (for ABS), can enhance the final fit and finish of the components.

Printer Compatibility & Settings

The Shush Puppy is compatible with most FDM 3D printers capable of handling detailed prints, such as Ender 3, Prusa i3, or similar models. Recommended materials include PETG for its balance of strength and flexibility, or ABS for higher durability, though proper ventilation is required due to fumes. Avoid PLA due to its lower heat resistance, which may not withstand suppressor conditions.

Optimal print settings include a layer height of 0.2mm, 50-60% infill for structural integrity, and a nozzle temperature suited to the chosen material (around 230-250°C for PETG, 240-260°C for ABS). Ensure your printer bed is leveled and adhesion is strong to prevent print failures. For additional guidance, refer to the build instructions PDF available at the provided link.

Conclusion

The Shush Puppy redefines DIY suppressor creation with its innovative modular design and minimal reliance on external parts, making it a must-have for 3D printing and firearms enthusiasts. Its focus on accessibility and maintenance ease ensures that builders can craft a reliable 9mm suppressor without navigating complex regulatory or sourcing challenges.
