The Cobra 40 - 3D Printable SW40 Frame Parts

This downloadable file includes the STL files necessary to print the Cobra 40 frame, designed specifically for S&W SD40 and SW40 builds. For optimal results, we recommend printing with a high infill percentage (80-100%) to ensure structural integrity, especially in high-stress areas. Consider using durable materials like PETG or ABS for longevity and impact resistance.

Pay attention to layer height (0.1-0.2mm recommended) for smoother finishes and tighter tolerances. Post-processing, such as sanding or acetone smoothing (for ABS), can enhance the frame’s appearance and fit. Always double-check critical dimensions after printing to ensure compatibility with your parts kit.

Printer Compatibility & Settings

The Cobra 40 frame is compatible with most FDM 3D printers capable of handling detailed prints, such as Ender 3, Prusa i3, or similar models. For materials, PETG is highly recommended for its balance of strength and ease of printing, though ABS can be used for added durability if proper ventilation is available. Avoid PLA due to its brittleness under stress.

Set your printer to a nozzle temperature of 230-250°C (for PETG) or 240-260°C (for ABS), with a bed temperature of 80-100°C. Use supports for overhangs and a brim or raft for better bed adhesion. Ensure your printer’s build volume can accommodate the frame’s dimensions, typically fitting within a standard 220x220x250mm print area.
