Tired of struggling with expensive hardware or messy welds for your DIY structures? This is the Ultimate Parametric Connector System designed for Metalon (metal tubes), plastic pipes, or any structural tubing.

Whether you are building custom shelving, a photography rig, or a furniture frame, this OpenSCAD-powered generator creates the perfect fit for your specific needs.

🚀 Key Features:

Universal Support: Choose between Square, Round, or Rectangular profiles.
Fully Parametric: Adjust dimensions, wall thickness, and tolerances directly in the MakerWorld Customizer.
Robust Joint Logic: Includes 3D-Corners, T-Junctions, Crosses, and Straight connectors.
Internal Locking Ribs: Built-in "teeth" (ribs) ensure a tight, friction-fit grip inside the tube.
Professional Aesthetics: High-quality 3D rounded hubs for a premium, injection-molded look.
Stronger Prints: Features a Detachable Vertical Arm option, allowing you to print the Z-axis arms horizontally for maximum layer strength.

🔧 How to use:

Measure your tube's external dimensions and wall thickness.
Open the Customizer.
Adjust the tolerance based on your printer's accuracy (0.15mm is usually the sweet spot).
Export the STL and build your project!

🖨️ Printing Recommendations:

Material: PETG, ASA, or ABS (highly recommended for structural integrity).
Walls: 4 to 6 walls for maximum strength.
Infill: 40% or higher (Gyroid recommended).
Orientation: If using the detachable arm, print it lying down to ensure the locking ribs and the arm itself don't snap under stress.

🤝 Bug Reports & Improvements:

I am constantly refining this script, but if you encounter any issues or "bugs" during customization, please report them in the comments! I will do my absolute best to fix them and update the files promptly.

Also, feel free to remix and improve the code! This project is about helping the maker community. If you add a cool feature or optimize the logic, please share it back!
