OK Boomer - 3D Printed 1911 - v1.2

OK Boomer - 3D Printed 1911 - v1.2 Features

This innovative 3D printed 1911 frame stands out as the first FDM-printable design of its kind, developed over three years to deliver reliability under real-world use. It supports USGI and Para/Clark style ramped barrels, allowing builders to customize their pistols with proven barrel configurations for optimal performance.

Key features include:

• Proven Durability: Test models have endured over 2,000 rounds of .45 ACP, showcasing the frame's robustness for long-term shooting.
• Integrated Rails in v1.2: This update includes the essential rail models, correcting the initial release and ensuring a complete printable package.
• Caliber-Specific Compatibility: Designed with considerations for components like ejectors, which must match calibers such as .45 ACP or 9mm/.38 Super for proper fitting.

The frame's design emphasizes straightforward installation of external components, though minor fitting may be needed for parts like the ejector to accommodate pins and avoid pitfalls. Overall, it's a practical choice for 3D printing enthusiasts seeking a high-performance, printable 1911 frame that combines innovation with firearm tradition.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 10-20 hours (including printing, assembly, and fitting)
• Required Experience: Basic 3D printing knowledge and familiarity with firearm assembly; experience with fitting components like ejectors is recommended to handle potential minor adjustments.

Hardware and Tools Required

Required Hardware

• Correct ejector for your caliber (e.g., .45 ACP or 9mm/.38 Super, as differences exist and must be verified ahead of time)
• USGI or Para/Clark style ramped barrel for compatibility
• Standard 1911 components such as firing pin and other external frame parts
• Ejector pin for installation

Recommended Tools

• Drill bit for hand-turning through the ejector pin hole to mark relief areas
• File for creating small reliefs to accommodate the ejector pin
• Tools for chasing and fitting, such as those needed for minor adjustments during ejector installation

OK Boomer - 3D Printed 1911 - v1.2 Parts

This downloadable file includes the STL models for the original FDM 3D printable 1911 frame, with version 1.2 incorporating the essential rails that were omitted in the initial release. The package focuses on the frame as the core component, designed for integration with standard 1911 hardware.

For printing, use FDM-compatible settings with a recommended infill of 100% for maximum strength, given the frame's need to withstand high-stress use like firing over 2,000 rounds of .45 ACP. Suggested materials include durable filaments such as PETG or ABS to ensure longevity and heat resistance during operation. Special considerations include printing with supports for overhangs, and post-print finishing to smooth surfaces for better component fitting—refer to the provided build instructions PDF for detailed guidance on assembly and ejector installation steps.

Printer Compatibility & Settings

This design is optimized for FDM 3D printers, making it compatible with popular models like Ender 3, Prusa i3, or similar desktop printers capable of handling detailed firearm components. Recommended materials include PETG or ABS for their strength and ability to endure the rigors of .45 ACP firing, though PLA can be used for prototyping with caution due to lower durability.

Print settings should include a layer height of 0.2mm for precision, 100% infill for structural integrity, and a print speed of 40-60mm/s to avoid warping. Enable supports for complex areas like barrel ramps, and ensure a heated bed (around 60-80°C for PETG) to promote adhesion—always calibrate your printer to match the frame's requirements for USGI or Para/Clark barrel compatibility.

Conclusion

The OK Boomer - 3D Printed 1911 - v1.2 offers unmatched value for 3D printing and firearms enthusiasts, combining proven durability with easy customization for a reliable 1911 frame. Whether you're building for testing or long-term use, its support for over 2,000 rounds and included rails make it a standout choice in printable firearm designs.
