26 Features

The DD26.2 frame stands out with significant design improvements over the original FMDA spec. After extensive community feedback, this update eliminates the weak screw-in rear rails by integrating compatibility with high-quality commercial rail options.

• Enhanced Durability: Redesigned to address structural weaknesses, ensuring a more robust frame.
• Easier Assembly: Dimensional adjustments make the build process smoother and more user-friendly.
• Upper Compatibility: Fully compatible with G27 uppers, offering versatility for different builds.
• Gen5 Spring Option: The ‘G5Spring’ version supports a Glock Gen5 style spring setup for the slide latch, catering to modern preferences.

This frame leverages the rise of trusted rail vendors, allowing builders to skip crafting rails from scratch. It’s a perfect blend of DIY innovation and commercial reliability.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 8-12 hours
• Required Experience: Basic knowledge of 3D printing and firearm assembly recommended; familiarity with Glock frame components is a plus.

Hardware and Tools Required

Required Hardware

• DD26.2 frame (3D printed from provided STL files)
• Commercial rails (available from vendors like Avesrails.com or Riptiderails.com)
• Compatible G27 upper (or similar components)
• Glock Gen5 style spring setup (if using the ‘G5Spring’ frame version)
• Standard Glock frame assembly hardware (pins, screws, etc.)

Recommended Tools

• 3D printer for frame production
• Drill or Dremel for minor adjustments
• Screwdrivers or Allen keys for assembly
• Calipers for precise measurements
• Sandpaper or finishing tools for post-print cleanup

26 Parts

This downloadable file includes access to the DD26.2 Build Tutorial PDF, which details the assembly process for the Glock 26/27 frame. While the STL files for the frame itself are not included in this specific download, the guide references the necessary components and assumes access to the frame design for printing. For optimal results, print the frame using PETG or ABS materials to ensure durability and heat resistance, with a layer height of 0.2mm and at least 50% infill for structural integrity.

Consider printing with a brim or raft to prevent warping, especially for larger frame sections. Post-processing may involve sanding or minor drilling to achieve a perfect fit with commercial rails and other hardware. Always ensure your printer bed is leveled to avoid dimensional inaccuracies during printing.

Printer Compatibility & Settings

The DD26.2 frame design is compatible with most FDM 3D printers, including popular models like the Ender 3, Prusa i3, or Anycubic i3 Mega. For materials, PETG is highly recommended due to its balance of strength and flexibility, though ABS can also be used if proper ventilation is available due to fumes. Avoid PLA as it lacks the necessary durability for functional firearm components.

Set your printer to a nozzle temperature of 230-250°C for PETG (or 240-260°C for ABS) and a bed temperature of 80-90°C. Use a 0.2mm layer height with a minimum of 50% infill to ensure the frame can withstand mechanical stress. A cooling fan at 50-70% is advised for PETG to prevent overheating, and supports may be necessary for overhangs depending on your printer’s capabilities.

Conclusion

The DD26.2 Glock 26/27 Frame Build Tutorial is an essential resource for anyone looking to craft a custom firearm with improved design and assembly ease.
