Vacuum Attachment Adaptor

This project began with a practical problem: several attachments that came with my vacuum cleaner were incompatible with the suction outlet of the appliance,—the ends didn’t fit properly. Rather than discard them, I decided to design and fabricate a custom adapter that would bridge the gap between the vacuum's nozzle and the attachment ports, making the accessories fully usable.
The process started with measurements of both the vacuum and the attachments. I then created an initial sketch in Autodesk Inventor, and as the design evolved, I refined it with several thoughtful features. For instance, I added filleted transitions between internal surfaces to promote smoother airflow and prevent debris from catching in sharp corners. I also introduced a small indent at the edge of the adapter, allowing for an easier grip when detaching snug-fitting accessories—an ergonomic improvement that emerged after test-fitting the prototype.
The final product was printed using ABS filament on a Bambu X 3D printer. The geometry was optimized for clean printing, requiring only a raft and no support structures.
This project reflects my interest in improving everyday objects through design, combining precise fit, functional adaptation, and user-centered features to solve small but meaningful problems.
