Universal Parametric Manifold & Splitter Generator

One generator, infinite connection possibilities.

Create custom 1-to-Many splitters, manifolds, and distributors for any application.

Whether you are moving air, water, pellets, or cables, this parametric script generates the perfect smooth-flow geometry.

IDEAL FOR

• Airflow: Cooling ducts, ventilation, fan adapters.
• Fluids: Gravity-feed water lines, hydroponics, drain mergers.
• Solids: Seed distributors, pellet hopper splitters, marble runs.
• Workshop: Dust collection, shop vac manifolds.
• Organization: Cable routing and consolidation.

KEY FEATURES

Support-Free Printing

Engineered specifically for clean FDM printing:

• Auto-Invert: Flips the model to ensure a stable base.
• Flush Cut: Slices angled ports flat so they adhere perfectly to the print bed.
• Zero Supports: Print complex multi-port manifolds without wasting material (in many situations but not all).

Fully Custom Geometry

• Any Count: Split 1 line into 2, 3, 4, or even 10 outputs.
• Spread & Angle: Widen ports for fittings or angle them for smooth routing.
• Universal Sizes: Mix and match any input/output diameters (mm, inches, etc.).

HOW TO USE

1. Configure Ports

• Output Count: Choose how many branches you need.
• Flare Angle: Angle them outwards (15-45°) for better clearance.

2. Enter Sizes

• Side A (Main): The single input/output source.
• Side B (Branches): The multiple destination ports.

3. Print

• Check "Print Orientation" to maximize bed adhesion.
