Amigo Verde

Amigo Verde Features

The Amigo Verde stands out with its innovative hybrid design, merging the reliability of the CETME L with the versatility of AR15 components. This build simplifies assembly by incorporating modularity, allowing for easier customization and maintenance.

Key highlights include:

• 3D Printable Receiver: Split into upper and lower sections for seamless printing and assembly.
• CETME L Core Integration: Utilizes essential parts like the bolt carrier group, trunnion, barrel, recoil spring assembly, and charging handle for authenticity.
• AR15 Compatibility: Incorporates AR15 fire control parts, enhancing ease of use and part availability.
• Simplified Barrel Process: Features a unique barrel pressing and pinning method, detailed in the guide, which is notably easier than other CETME models.

This design prioritizes practicality, making it a standout choice for firearm enthusiasts looking to explore 3D printing projects.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 2-3 days (including printing and assembly)
• Required Experience: Basic knowledge of firearm assembly and 3D printing; familiarity with CETME or AR15 components is helpful but not mandatory.

Hardware and Tools Required

Required Hardware

• CETME L core components (bolt carrier group, trunnion, barrel, recoil spring assembly, charging handle)
• AR15 fire control group parts
• Standard fasteners and pins as detailed in the build tutorial

Recommended Tools

• 3D printer (compatible with recommended materials)
• Barrel pressing and pinning tools (specific guidance provided in the tutorial)
• Basic hand tools (screwdrivers, wrenches, etc.)
• Drill or press for precise assembly
• Finishing tools for post-print cleanup (sandpaper, files)

Amigo Verde Parts

The Amigo Verde package includes detailed STL files for the split upper and lower receiver components, designed specifically for 3D printing. These files are optimized for durability and fit, ensuring a reliable build when printed with the right settings. It’s recommended to use high-strength materials like PETG or ABS for the receiver parts to withstand the stresses of firearm use.

For best results, print with a layer height of 0.2mm and a high infill percentage (at least 50%) to ensure structural integrity. Pay attention to proper bed adhesion and support structures, as the receiver geometry may require supports for overhangs. Always double-check the fit of printed parts with hardware before final assembly to avoid issues.

Printer Compatibility & Settings

The Amigo Verde STL files are compatible with most FDM 3D printers, including popular models like the Ender 3, Prusa i3, or similar machines with a build volume of at least 220x220x250mm. For materials, PETG or ABS are strongly recommended due to their strength and heat resistance, which are critical for firearm components. PLA is not advised as it lacks the necessary durability for this application.

Optimal print settings include a nozzle temperature of 230-250°C for PETG or 240-260°C for ABS, a bed temperature of 80-100°C, and a print speed of 40-60mm/s to maintain accuracy. Ensure proper cooling and ventilation, especially when printing with ABS, to avoid warping. If your printer struggles with complex geometries, consider using supports and a brim for better adhesion during printing.
