TMS-FNS 3D Printable FNS40/FNS9 + FN509 Frame

TMS-FNS 3D Printable FNS40/FNS9 + FN509 Frame Features

The TMS-FNS Frame stands out with a host of functional and aesthetic upgrades tailored for optimal performance. This design incorporates tightened sear assembly pockets for better stability and a looser tolerance for the Magwell to ensure smoother magazine insertion. The frame also features a thickened front locking block pin area and rear sear assembly/rail pin area, with a suggestion to use a longer roll pin to maximize the added material strength.

Cosmetically, this frame is a game-changer with extensive grip shaping and P80-style trigger guard for a modern look. Additional highlights include:

• Thickened frame sides with stippling sections for improved grip texture.
• Added ribs on the grip for enhanced comfort and control.
• A totally unique yet familiar design that balances innovation with tradition.

These modifications make the TMS-FNS Frame a practical and visually striking choice for your next 3D printed firearm project.

TMS-FNS 3D Printable FNS40/FNS9 + FN509 Frame Parts

This downloadable file includes the STL files necessary to print the TMS-FNS Frame for FNS40, FNS9, and FN509 models. The design has been optimized for durability with thickened areas and functional tweaks like an adjusted mag release on the horizontal axis and a larger shelf for trigger safety. While the original instructions suggest printing Magwell down, the developer notes alternative orientations work well—just ensure thorough support removal for a clean finish.

For best results, use high-strength materials like PETG or ABS to withstand the mechanical stress of firearm use. Detailed build instructions are available as a PDF guide at this link to assist with assembly and finishing.

Printer Compatibility & Settings

The TMS-FNS Frame is compatible with most FDM 3D printers that have a sufficient build volume to accommodate the frame dimensions. Recommended materials include PETG or ABS for their strength and heat resistance, critical for firearm applications. Avoid weaker materials like PLA, as they may not endure the operational stresses.

Print settings should prioritize high infill (80-100%) and a layer height of 0.2mm or lower for optimal detail and structural integrity. Ensure proper bed adhesion and consider using a brim or raft to prevent warping during printing. Post-processing, such as support removal and sanding, is crucial for a functional fit, as noted by the developer’s advice to “clean out your supports ya noob.”

Conclusion

The TMS-FNS 3D Printable FNS40/FNS9 + FN509 Frame is an exceptional choice for firearm enthusiasts eager to customize their builds with a blend of functionality and style.
