This 3D printable frame stands out with its organic, sculpted design that prioritizes ergonomics, eliminating flat surfaces for a more natural feel during handling and carry. Unlike standard Glock frames, the PP43XO features a molded grip that enhances comfort, making it ideal for extended use in concealed carry scenarios.

High Reliability: When paired with OEM slides and parts, it achieves 100% reliability comparable to a factory G43X.
Custom Fit Options: Includes longer versions to accommodate G48 slides, expanding versatility for different builds.
Magazine Compatibility: Works seamlessly with Shield Arms S15, PSA Dagger Micro, or OEM magazines for reliable feeding.
Bonus Holster Inclusion: Comes with a second-generation AIWB holster design that fits PP43XO, OEM Glock 43X/48, and similar frames, featuring improved clip retention and simplified hardware needs.

The holster's updates make it more user-friendly, requiring only three sets of M3 nuts and bolts—no Chicago screws or rubber washers needed. This combination of frame and holster creates a complete, printable solution for CCW enthusiasts.

PP43XO - Printable Glock 43X - DD43.1 / SS80 rails Parts

The download includes STL files for the PP43XO frame, with options for standard and longer versions to fit G43X or G48 slides, ensuring flexibility in your build. It also features STEP files for the AIWB holster in left- and right-handed configurations, plus a 3MF file optimized for OrcaSlicer or Bambu Studio. Recommended print settings emphasize durability: use nylon/CF for the frame to achieve factory-level reliability, and print the holster body nose down with the clip standing on one side as pre-oriented in the STLs.

Material suggestions include PLA+ or nylon CF/GF for the holster to balance strength and comfort. Special considerations involve following the provided orientations to minimize supports and ensure a tight fit for the frame's ergonomic surfaces. For detailed assembly, refer to the included PDF guide covering printing and build steps.

Printer Compatibility & Settings

This design is compatible with most FDM 3D printers, such as those from Prusa, Ender, or Bambu Labs, provided they support durable filaments. Recommended materials are nylon/CF for the frame to ensure reliability and ergonomics, while PLA+ or nylon CF/GF works well for the holster components.

Print settings should include a layer height of 0.2mm for detail, infill of 20-40% for strength, and no supports if following pre-oriented STLs—print at temperatures suitable for your filament (e.g., 240-260°C for nylon blends). Special requirements include using a heated enclosure for nylon to prevent warping, and ensuring good bed adhesion for stable prints.

Conclusion

The PP43XO delivers an unmatched blend of comfort, reliability, and customization for 3D printing enthusiasts building their ideal Glock 43X-based CCW. With its ergonomic design, included holster, and compatibility with popular rails and magazines, it empowers users to create a firearm frame that feels superior to OEM options.
