A Mechanical Freelancing Hub

We need a functional mechanical adapter for a canister vacuum cleaner that interfaces with the existing vacuum outlet and supports interchangeable tool attachments, specifically a crevice tool.

* Application: Canister vacuum cleaner accessory
* Function: Vacuum outlet-to-tool interface with interchangeable attachment capability
* Primary attachment: Crevice tool
* Design requirements: Secure fit, proper airflow passage, dimensional compatibility, and easy attachment/removal
* Mechanical considerations: Mating diameters, insertion depth, retention features, wall thickness, clearances, and joint strength

Deliverable: Production-ready 3D CAD model suitable for 3D printing/prototyping and functional testing
