The Glong by YZY Prints

The Glong by YZY Prints Features

The Glong stands out as a bold statement piece in the realm of 3D printed firearms, blending functionality with a deeper social message. Its design draws inspiration from the FMDA DD17.2 Glock 17 frame updates, incorporating refined dimensions for easier assembly and enhanced durability.

Key highlights include:

• Cultural Impact: Reflects the FOSSCAD mission to democratize small arms production while addressing issues like marijuana legality and systemic inequality.
• Compatibility: Works seamlessly with G22 uppers, offering flexibility for builders.
• Community-Driven Design: Builds on feedback from the DIY community to improve weak points like rear rails, ensuring a more robust frame.

This remix, including the G26 XXXL Glong variant by Chairmanwon, showcases the evolving nature of open-source firearm projects. It’s a must-have for those passionate about pushing boundaries in both technology and advocacy.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 10-15 hours
• Required Experience: Familiarity with 3D printing and basic firearm assembly; prior experience with Glock frames or FMDA designs is recommended.

Hardware and Tools Required

Required Hardware

• Glock-compatible upper (G22 compatible as per design specs)
• Quality rails (sourced from vendors like Avesrails.com or Riptiderails.com)
• Gen5 style spring setup (optional, for the G5Spring frame version)
• Standard Glock frame assembly components (refer to FMDA DD17.2 Assembly Tutorial for full shopping list)

Recommended Tools

• 3D printer with suitable bed size and material compatibility
• Screwdrivers and Allen keys for assembly
• Drill or Dremel for minor frame adjustments
• Calipers for precise measurements during build
• Sandpaper or finishing tools for post-print smoothing

The Glong by YZY Prints Parts

The Glong by YZY Prints includes STL files for the main frame, with the recent addition of the G26 XXXL Glong remix by Chairmanwon in a dedicated folder. These files are designed for compatibility with Glock uppers, ensuring a reliable fit when printed correctly. For optimal results, use a high-strength material like PETG or ABS, with a layer height of 0.2mm and at least 50% infill to ensure structural integrity.

Pay attention to the rear rail sections, as they’ve been refined based on community feedback to address past weak points. Print with adequate cooling to prevent warping, especially on larger components. Refer to the FMDA DD17.2 Assembly Tutorial PDF for detailed build guidance, available at the provided link.

Printer Compatibility & Settings

The Glong by YZY Prints is compatible with most FDM 3D printers that have a build volume sufficient for Glock frame dimensions (check specific STL requirements). Recommended materials include PETG or ABS for their strength and heat resistance, though advanced users may opt for nylon blends for added durability. Print settings should prioritize a 0.2mm layer height, 50-70% infill, and 3-4 wall lines for robustness.

Ensure your printer bed is leveled and use a brim or raft if adhesion issues arise. High-quality filament and consistent cooling are critical to avoid deformation during long prints. Always test-fit components post-print to confirm dimensional accuracy before final assembly.

Conclusion

The Glong by YZY Prints is more than a 3D printable firearm frame—it’s a symbol of innovation, advocacy, and community resilience in the face of legal and social challenges. Perfect for intermediate builders, this design offers a rewarding project that combines technical skill with a powerful message.
