• Easy to print and assemble
• Customizable for different projects
• Reduces manufacturing and assembly cost

Recommended Printing Parameters

• Material: PETG, PLA+, ABS, Nylon (PETG/Nylon preferred for strength)
• Layer Height: 0.2–0.28 mm
• Nozzle: 0.4 mm (0.6 mm for higher strength)
• Walls: 4–6 perimeters
• Infill: 35–60% (Gyroid/Cubic)
• Print Speed: 40–60 mm/s
• Orientation: Flat on bed for maximum strength

Applications

• 3D printer frames
• CNC and automation structures
• Robotics chassis
• Educational kits
• Modular furniture

Performance

• High dimensional accuracy
• Good load distribution
• Load capacity up to ~25–60 kg (material dependent)
• Long-term structural stability

Future-Ready Potential

• Parametric resizing
• Smart sensor integration
• AI-based structural optimization
• Support for automated manufacturing workflows

In summary, this connector enables fast, strong, and customizable frame construction using standard 3D printers, making it suitable for both prototyping and semi-industrial applications.
