DD20.1 - 3D Printable Glock 20/21 Frame

DD20.1 - 3D Printable Glock 20/21 Frame Features

The DD20.1 frame stands out with its refined design updates, drawing inspiration from community feedback and advancements seen in similar projects like the DD17.2. This frame addresses common weak points found in earlier DIY Glock frames, ensuring a more durable and user-friendly build.

Key highlights include:

• Enhanced Structural Integrity: Improved dimensional tweaks for easier assembly and a stronger overall frame.
• Upper Compatibility: Seamlessly works with Glock 20 and 21 uppers for versatile builds.
• Community-Driven Innovation: Incorporates feedback from extensive testing to optimize performance.

This design leverages the availability of quality commercial rails from vendors like Avesrails.com and Riptiderails.com, eliminating the need for custom rail fabrication. It’s a practical choice for anyone aiming to create a functional and reliable firearm frame with minimal hassle.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days (including printing and assembly)
• Required Experience: Basic knowledge of 3D printing and firearm assembly; familiarity with Glock components is recommended.

Hardware and Tools Required

Required Hardware

• Glock 20 or 21 upper components (slide, barrel, etc.)
• Commercial rails (available from vendors like Avesrails.com or Riptiderails.com)
• Standard Glock frame hardware (pins, springs, etc.)
• Fasteners and screws compatible with the frame design

Recommended Tools

• 3D printer with a build volume suitable for the frame dimensions
• Screwdrivers and Allen keys for assembly
• Sandpaper or finishing tools for post-processing
• Drill (if minor adjustments are needed for fitment)

DD20.1 - 3D Printable Glock 20/21 Frame Parts

This downloadable file includes the STL files necessary to print the DD20.1 Glock 20/21 frame, designed for a precise fit with compatible uppers. For optimal results, print with a high infill percentage (80-100%) to ensure strength and durability under stress. We recommend using PETG or ABS filament for their balance of toughness and heat resistance, critical for firearm applications.

Pay attention to layer adhesion during printing, as this frame will endure mechanical stress. Post-processing, such as sanding or acetone smoothing (for ABS), can improve aesthetics and fitment. Always test-fit components before final assembly to avoid issues.

Printer Compatibility & Settings

The DD20.1 frame is compatible with most FDM 3D printers that have a sufficient build volume to accommodate the frame’s dimensions. Recommended materials include PETG or ABS due to their strength and resistance to wear, though advanced users may experiment with nylon for added durability. Avoid PLA, as it lacks the necessary toughness for functional firearm parts.

Suggested print settings include a layer height of 0.2mm, 80-100% infill, and a minimum of 4-6 wall layers for structural integrity. Ensure your printer bed is leveled and use a brim or raft if adhesion issues arise. For detailed build instructions, refer to the PDF guide available at this link.
