Universal Modular Pipe Connector

Build anything — shelving units, greenhouse frames, display racks, tent structures, or robot chassis — with one parametric connector that adapts to your exact pipe size. This fully parametric OpenSCAD model generates 3-way, 4-way, 5-way, and 6-way pipe connectors with a single click. Just enter your pipe's outer diameter and the connector does the rest. ✨ Key Features 5 Connector Modes — 3-Way Corner, 4-Way Flat Cross, 4-Way Corner, 5-Way Hub, and 6-Way Universal Hub. Any Pipe Size — Works with PVC pipes, aluminum tubes, carbon fiber rods, wooden dowels, or copper tubing. Just enter the outer diameter. Structural Gussets — Optional reinforcement ribs between adjacent arms for maximum joint rigidity under load. Precision Tolerance Control — Dial in a snug press-fit (0.1mm) or a loose sliding fit (0.4mm) depending on your application. Flat Base for Printing — Horizontal arms sit flat on the build plate at Z=0. No wasted supports on the underside. Through-Bore Design — Hollow all the way
