AR-15 Super Lower V3.1 Parts
The AR-15 Super Lower V3.1 download includes a comprehensive set of STL files for both the "Super Lower" (SL) and "Basic Lower" (BL) variants. File naming conventions like "NS" (No Support) and "WS" (With Support) help you choose the best option for your printer setup. For detailed design specifics, refer to the included INFO text file.
Hoffman Tactical recommends reviewing the README file for generic print settings and guidance. Using strong, durable materials is advised to ensure the lower receiver withstands operational stress. Pay attention to layer adhesion and infill density for optimal results.
Build instructions are also provided as a PDF guide, accessible at this link, to assist with assembly.
Printer Compatibility & Settings
The AR-15 Super Lower V3.1 files are compatible with most FDM 3D printers capable of handling detailed prints. Recommended materials include PETG or ABS for their strength and heat resistance, though high-strength PLA+ can work for less demanding builds. Avoid standard PLA due to its brittleness.
Set your printer to a high infill percentage (50-100%) for structural integrity, and use a layer height of 0.2mm or finer for precision. Ensure proper bed adhesion and consider using supports if opting for the "NS" files. Always refer to the README for generic settings and adjust based on your printer's capabilities.
Conclusion
The AR-15 Super Lower V3.1 by Hoffman Tactical is an exceptional resource for 3D printing and firearms enthusiasts looking to build a custom AR-15 lower receiver. With its thoughtful updates, organized files, and detailed guidance, this download simplifies the journey from concept to completion.
