Twist Tube Connector CAD Design

I have a concept for a tube-to-tube adapter that functions as a twist connector coupling, and I need it translated into clear, production-ready CAD. The job is straightforward: create a fully detailed 3D model along with a clean 2D drawing set that can go straight to machining or 3-D printing.

Scope
• Model a twist-style tube coupling that joins two tubes securely.
• Make the design fully parametric so wall thickness or bore can be adjusted later.
• Produce 2D manufacturing drawings with all key dimensions, tolerances, and a short BOM if any fasteners or seals are required.

Deliverables
1. Native CAD file (SolidWorks, Fusion 360, or Inventor) plus neutral formats (STEP and IGES).
2. PDF drawing pack showing orthographic views, section view of the twist-lock feature, and an isometric for reference.

Acceptance Criteria
• Parts mate without interference in the 3D assembly.
• Drawings call out critical fits for the twist mechanism.
• All files open error-free in the latest version of the chosen CAD package.

If you have suggestions on improving the twist-lock engagement or simplifying manufacturing, I’m happy to hear them; otherwise, keep strictly to the coupling concept described above.
