Basic Splitter Design Needed

I need a straightforward splitter designed from scratch and I’m still open on every key variable—material, dimensions, and even the exact application. Whether the final piece ends up in plastic, metal, or wood, what matters most is turning a simple “one input, multiple output” idea into a clean, manufacturable solution.

Here’s what I’m expecting from you:
• A 3D CAD model built in SolidWorks, Fusion 360, or comparable software
• Dimensioned 2D drawings ready for fabrication or rapid prototyping
• A brief bill of materials noting suggested stock sizes and finishes
• Up to two revision cycles so we can tweak form factor or tolerances once I review the first draft

If you’re comfortable selecting appropriate wall thicknesses, draft angles, or coupling hardware to match the chosen material—and you can walk me through the trade-offs between cost, durability, and ease of manufacture—let’s get started.
