The FMDA DD19.2 3D Printable Glock Frame
Overview
The FMDA DD19.2 represents a significant evolution in 3D printable Glock frame design, incorporating over a year of real-world testing and community feedback. This updated frame addresses the weak points of first-generation designs while maintaining compatibility with both Glock 19 and G23 uppers.
Built by the Firearms Manufacturers and Dealers Association (FMDA), this frame leverages commercial rail solutions and refined dimensional specifications to deliver easier assembly and improved reliability. The DD19.2 eliminates problematic screw-in rear rails while incorporating dimensional tweaks that streamline the build process for makers of all skill levels.
The FMDA DD19.2 3D Printable Glock Frame Features
The DD19.2 frame design represents a complete overhaul of the original DIY spec Glock frame, with enhanced structural integrity replacing the problematic screw-in rear rail system that proved to be a weak point in earlier iterations.
Dimensional refinements throughout the frame geometry make assembly significantly easier compared to first-generation designs. The frame incorporates commercial rail compatibility with vendors like Avesrails.com and Riptiderails.com, eliminating the need for scratch-built rail solutions.
Key design improvements include:
- Dual compatibility with both Glock 19 and G23 uppers
- G5Spring frame version available with Glock Gen5 style spring setup for slide operation
- Refined trigger guard geometry for improved ergonomics
- Optimized support structures for reliable 3D printing

The FMDA DD19.2 3D Printable Glock Frame Parts
The STL package includes the main frame geometry optimized for FDM printing with standard 0.4mm nozzles. Print orientation follows rails-down methodology for optimal layer adhesion in critical stress areas.
Material recommendations include PLA+ for initial testing and ABS or PETG for final builds requiring enhanced durability. The frame design incorporates built-in support structures in critical areas while minimizing the need for external supports.
Layer height settings of 0.2mm provide the optimal balance between print time and surface finish, while infill percentages of 99-100% ensure maximum structural integrity in load-bearing areas.
Printer Compatibility & Settings
The DD19.2 frame is compatible with most FDM printers with a minimum build volume of 200mm x 150mm x 50mm. Enclosed printers are recommended for ABS printing to prevent warping and ensure dimensional accuracy.
Recommended print settings include 0.2mm layer height, 99% infill density, and three perimeter walls minimum for structural integrity. Print temperature varies by material: PLA+ at 215-220°C, ABS at 240-250°C, and PETG at 235-245°C.
Bed adhesion is critical for this large print, with heated beds recommended at 60°C for PLA+ and 80-100°C for ABS materials.
Conclusion
The FMDA DD19.2 represents a mature evolution in 3D printable frame design, incorporating extensive real-world feedback and testing data. With its commercial rail compatibility and refined assembly process, this frame offers builders a reliable platform that addresses the shortcomings of earlier generations.
