FTN.3 EZ Suppressor Pack v1.1
Overview
Discover the FTN.3 EZ Suppressor Pack v1.1, a downloadable 3D printed suppressor design that's perfect for firearms enthusiasts seeking a simple, effective noise reduction solution without the hassle of complex builds. This free file empowers you to create a rifle-rated suppressor at home, rated for calibers like 9mm, 556, 300blk, and even 308 in the standard size, making it a valuable resource for both beginners and seasoned builders looking to enhance their shooting experience.
The purpose of this design is to simplify the original FTN.3 suppressor by offering an easy-to-print polygon shape that eliminates the need for resin mixing and custom sourcing. It functions as a durable, wrap-friendly suppressor with secure endcaps, providing reliable performance across multiple calibers including 7.62x39. Key benefits include reduced complexity for new printers, a "keep it simple" approach with just two sizes (standard and K short), and the use of superior 3M casting tape for a tight, secure wrap without messy resins.
FTN.3 EZ Suppressor Pack v1.1 Features
This suppressor pack stands out with its polygon-shaped design, which makes 3D printing straightforward and eliminates the intricate details that can complicate builds. Unlike the original FTN.3, it focuses on practicality by offering only essential options, ensuring a hassle-free experience for users who prefer simplicity over extensive customization.
- Caliber Ratings: Rated for 556, 7.62x39, 300, and 9mm; the standard size also handles 308, while the K size remains untested for 308.
- Simplified Sizing and Threading: Available in just two sizes—standard and K (short)—with a single threading option using a thread adapter for easy firearm compatibility.
- Easy Wrapping System: No resin mixing required; uses 3M casting tape, which is superior to alternatives like JB Fiberweld for achieving a tight wrap and securing endcaps.
- User-Friendly for New Printers: Designed as a "keep it simple" version, ideal for those avoiding tinkering, with an emphasis on careful assembly to ensure safety and performance.
These features make the FTN.3 EZ a practical choice for 3D printing enthusiasts building suppressors that are both functional and easy to assemble.

FTN.3 EZ Suppressor Pack v1.1 Parts
The pack includes STL files for the FTN.3 EZ suppressor components, designed in an easy-to-print polygon shape that reduces printing errors and supports straightforward assembly. Key parts cover the standard and K sizes, with elements like the main body, endcaps, and thread adapter. For optimal results, print with infill settings around 100% for durability, and consider scaling based on your firearm's needs.
Material suggestions lean toward strong filaments suitable for high-stress applications, ensuring the suppressor withstands rated calibers like 556 and 9mm. Special considerations include printing in a well-ventilated area and double-checking layer adhesion to maintain structural integrity during wrapping with 3M casting tape.
Printer Compatibility & Settings
This design is compatible with most FDM 3D printers, including newer models, thanks to its simplified polygon shape that minimizes overhangs and supports easier printing. Recommended materials include PETG or ABS for their heat resistance and strength, ideal for a suppressor rated for calibers like 300blk and 308. Use print settings such as 0.2mm layer height, 100% infill, and a nozzle temperature of 220-240°C depending on the material; no special requirements beyond standard calibration to ensure precise fits for the thread adapter and endcaps.
Conclusion
The FTN.3 EZ Suppressor Pack v1.1 delivers key benefits like simplified printing, no-resin wrapping, and broad caliber compatibility, making it an accessible option for creating a reliable 3D printed suppressor. As a free design, it emphasizes safety and precision, so always prioritize reading the assembly PDF and videos to avoid issues.
