Hardware and Tools Required

Required Hardware

• Glock 33-round magazine spring or equivalent (for printed mags)
• JB Weld Clear Weld (for Sten mag latch installation)
• Metal Sten magazine (optional, if not using printed mags)

Recommended Tools

• 3D printer with compatible filament
• File or sandpaper (for fitting and finishing parts)
• C-clamp (for securing Sten latch during drying)
• Cleaning supplies (to remove residue and oil from mags)

DB Alloy 3D Printable MAC11-9 Lower Receiver Parts

This downloadable file includes STL files for all necessary components of the MAC11-9 lower receiver, such as the main body and magazine parts (body, follower, baseplate, and lock). For those using a metal Sten mag, a specific Sten latch STL is provided for modification. The files are pre-oriented for printing, ensuring ease of use straight out of the download.

It’s recommended to use PLA+ or stronger filament to ensure durability and functionality of the printed parts. Pay attention to post-print fitting, as minor filing may be required for the Sten latch or mag lips to interface correctly with the firearm’s bolt and catch. For detailed build instructions, refer to the PDF guide available at this link.

Printer Compatibility & Settings

The DB Alloy 3D Printable MAC11-9 Lower Receiver is compatible with most FDM 3D printers capable of handling detailed firearm components. Recommended materials include PLA+ or stronger filaments like PETG or ABS to withstand the mechanical stress of assembly and use. Ensure your printer bed is leveled and adhesion is optimal, as the pre-oriented STL files are designed for straightforward printing.

Use standard print settings with a layer height of 0.2mm for a balance of detail and speed, and consider a 20-30% infill for structural integrity. A brim or raft may be necessary for smaller components like the follower or latch to prevent warping. Always test-fit printed parts before final assembly to avoid binding issues.

Conclusion

The DB Alloy 3D Printable MAC11-9 Lower Receiver is a must-have for 3D printing and firearms enthusiasts seeking a customizable, community-supported design.
