This downloadable file offers firearms enthusiasts and 3D printing hobbyists a unique opportunity to build a reinforced 37mm launcher with optional metal enhancements for superior durability.
This design is tailored for those seeking a robust and customizable build, featuring options for a metal breach face and hinge reinforcements. Whether you're upgrading an existing project or starting fresh, the MCRN Boarder provides the strength and precision needed for a high-performance result. Its detailed addendum and assembly guidance make it a standout choice for serious builders.
MCRN Boarder: 37mm Features
The MCRN Boarder: 37mm stands out with its innovative reinforcement options, allowing users to integrate metal components for enhanced structural integrity. This remix builds on the NT-79 foundation, offering a more durable receiver and firing pin assembly for those tackling demanding projects.
Key highlights include:
- Metal Breach Face Option: Incorporate a 3.18mm thick metal plate (like 6061 aluminum) for unmatched strength compared to plastic alternatives.
- Hinge Reinforcements: Add metal hinge plates to ensure longevity and stability during use.
- Customizable Assembly: Choose between standard and reinforced components based on your build preferences.
This design is perfect for enthusiasts who prioritize durability and precision in their 3D-printed firearms projects. With detailed documentation, it bridges the gap between hobbyist experimentation and professional-grade results.
Difficulty & Build Time
- Skill Level: Intermediate
- Estimated Build Time: 12-16 hours
- Required Experience: Familiarity with 3D printing, basic metalworking (for tapping holes), and assembly of multi-part designs
Hardware and Tools Required
Required Hardware
- 1x additional 4mm rod cut to 50mm
- 2x M4x30mm socket head screws
- 1x Breach Plate DXF (3.18mm thick metal, e.g., 6061 aluminum, with M4 tapped holes)
- 2x Hinge Plate DXF (3.18mm thick metal, e.g., 6061 aluminum)
Recommended Tools
- 3D printer for printing components
- Metal cutting and tapping tools (if not outsourcing to services like Send Cut Send)
- Screwdrivers or Allen keys for socket head screws
- Measuring tools for precise rod cutting
- Assembly tools as per the NT-79 Assembly Guide PDF
MCRN Boarder: 37mm Parts
The MCRN Boarder: 37mm file set includes modified STL files for a reinforced build, ensuring compatibility with metal enhancements. Key substitutions include the Receiver_Reinforced file from the Reinforced directory (replacing the standard Receiver from Big Bits) and the Reduced_Cover file from the Reinforced directory (replacing the B-Firing Pin Bolt Face Cover from Little Bits). These files are designed to integrate seamlessly with the metal breach and hinge plates for a sturdy assembly.
For optimal results, print with high-strength materials like PETG or ABS to complement the metal reinforcements. Use a layer height of 0.2mm for detailed components and ensure proper bed adhesion to avoid warping. Refer to the provided build instructions for assembly specifics, available at the NT-79 Assembly Guide PDF.
Printer Compatibility & Settings
The MCRN Boarder: 37mm files are compatible with most FDM 3D printers capable of handling detailed multi-part designs, such as Ender 3, Prusa i3, or similar models. For materials, PETG or ABS is recommended due to their strength and heat resistance, which pair well with the metal reinforcements. Avoid PLA for functional parts as it lacks the durability needed for this project.
Suggested print settings include a 0.2mm layer height, 20-30% infill for structural integrity, and supports enabled for complex geometries. Ensure your printer bed is leveled and heated (60-80°C for PETG, 90-110°C for ABS) to prevent warping. Calibration of retraction settings is advised to minimize stringing on smaller components.
Conclusion
The MCRN Boarder: 37mm is an exceptional choice for 3D printing and firearms enthusiasts looking to elevate their builds with reinforced, durable designs. Its integration of metal components and detailed assembly guidance ensures a professional-grade outcome for intermediate builders.
