The Amigo Grande - 3D Printable CETME C 308 Receiver Parts

This downloadable file includes the STL files necessary to print the Amigo Grande CETME C 308 Receiver and the bonus "Nadda Spuhr" Spuhr-style stock. For optimal results, print with high infill settings (at least 50-75%) to ensure structural integrity under the stress of firearm operation. Using a strong filament like PETG or ABS is highly recommended for durability.

Special considerations include ensuring proper alignment during printing to avoid warping, as precision is critical for fitting with parts kits. A detailed build tutorial PDF is also available at the provided link to guide you through the assembly process step-by-step. Double-check layer adhesion and test-fit components before final assembly to guarantee a seamless build.

Printer Compatibility & Settings

The Amigo Grande receiver files are compatible with most FDM 3D printers that have a sufficient build volume to accommodate the receiver’s dimensions. Recommended materials include PETG or ABS for their strength and heat resistance, essential for firearm components. PLA is not advised due to its lower durability.

Optimal print settings include a layer height of 0.2-0.3mm, high infill (50-75%), and a heated bed to prevent warping. Ensure your printer is well-calibrated, and consider using a brim or raft for better bed adhesion. Post-processing may involve sanding or minor fitting to achieve a perfect match with your parts kit.
