The Grockson
Overview
Unlock the potential of DIY firearms with The Grockson, a cutting-edge update to the FMDA DD19.2 Glock 19 frame that empowers 3D printing enthusiasts to build reliable, custom handguns at home. This downloadable assembly tutorial provides step-by-step guidance, making it easier than ever to create a high-quality frame that's been refined based on real-world feedback from the firearms community.
The purpose of The Grockson is to address key weaknesses in the original DIY Glock frame design, such as the problematic screw-in rear rails, while incorporating dimensional adjustments for smoother assembly. It leverages commercial rail options from trusted vendors like Avesrails.com and Riptiderails.com, eliminating the need for scratch-built rails and enhancing overall durability. Key benefits include improved compatibility with G23 uppers, a more user-friendly build process, and options like the 'G5Spring' version for Gen5-style slide latch springs, delivering a practical solution for both novice and experienced builders in the 3D printed firearms space.
The Grockson Features
The Grockson stands out as an updated DIY Glock 19 frame that resolves common pain points from the first-generation design, drawing on over a year of community testing and feedback. By eliminating the weak screw-in rear rails and integrating refinements for easier assembly, it offers a more robust and reliable Stuart-friendly structure. Its compatibility with G23 uppers expands its versatility, allowing users to adapt it for different calibers without major modifications.
Key features include:
- Dimensional tweaks for simplified assembly, reducing frustration during the build process.
- Leverage of commercial rails from vendors like Avesrails.com and Riptiderails.com, ensuring high-quality components without DIY fabrication.
- Gen5-style spring setup in the 'G5Spring' variant, providing modern slide latch functionality for enhanced performance.
- Cross-compatibility with DD17.2 assembly steps, making the tutorial versatile for similar frames.
This design emphasizes practicality, with refinements that make it a go-to choice for 3D printing and firearms enthusiasts seeking reliability in home-built projects.
Difficulty & Build Time
- Skill Level: Intermediate
- Estimated Build Time: 4-6 hours
- Required Experience: Basic knowledge of 3D printing, familiarity with Glock-style firearms assembly, and access to commercial rails; prior experience with DIY frame builds recommended for best results
Hardware and Tools Required
Required Hardware
- 3D printed DD19.2 frame (or compatible variant like 'G5Spring' for Gen5 spring setup)
- Commercial rear rails from vendors such as Avesrails.com or Riptiderails.com
- Compatible G23 upper assembly for expanded functionality
- Standard Glock 19 internals, including slide latch spring (Gen5 style for specific versions)
Recommended Tools
- Screwdrivers and pliers for rail installation and frame assembly
- Files or sandpaper for any necessary dimensional adjustments
- Drill or Dremel tool for precise fitting of components
- Safety equipment like gloves and eye protection for handling parts
The Grockson Parts
The Grockson assembly tutorial references the DD19.2 frame as the core component, which users can 3D print using provided STL files (not included in the PDF but commonly available in DIY communities). Recommended print settings include a layer height of 0.2mm for detail and strength, with infill at 100% for durability in high-stress areas like the rail mounts. Material suggestions lean toward tough filaments like PETG or nylon for heat resistance and impact strength, with special considerations for printing in an enclosed environment to prevent warping during the process.
The tutorial outlines assembly of parts such as the rear rails, slide latch, and spring mechanisms, noting that steps mirror those for the DD17.2 frame. For the 'G5Spring' version, ensure the frame accommodates the Gen5-style spring setup. Always verify local laws before printing or assembling firearm components.
Printer Compatibility & Settings
The Grockson frame is compatible with most FDM 3D printers, including popular models like Ender 3 or Prusa series, as long as they support precise extrusion for detailed features. Recommended materials include PETG for its balance of strength and flexibility, or ABS for higher heat tolerance in firearm applications; avoid brittle options like PLA for structural integrity. Use settings such as 0.4mm nozzle, 200-220°C print temperature, 60-80mm/s speed, and full infill to ensure the frame withstands assembly stresses, with supports enabled for overhangs in the rail areas.
Conclusion
The Grockson delivers exceptional value for 3D printing and firearms enthusiasts by combining community-driven improvements with easy access to commercial parts, resulting in a more reliable and assemble-friendly Glock 19 frame. Whether you're upgrading from the original design or exploring G23 compatibility, this tutorial streamlines the process for impressive DIY results. Download the PDF guide today, source your rails
