3D printed upgrade for an old 80*25 fan v2.40mm

This is the third step of my fan-upgrade project. https://grabcad.com/library/3d-printed-upgrade-for-an-old-80-25-fan-v2-40mm-1 The purpose of this project is to breathe new life into an old, noisy 80*25mm fan commonly used in computers and other electronic devices. To achieve this, I plan to cut the central holding plate (motor legs) of your noisy 80mm fan and attach it to a central pad on the 3D printed body using double-sided adhesive foam or flexible glue. The foam/glue will absorb the fan's vibrations, resulting in a new silent turbine-blower for your projects. https://www.youtube.com/watch?v=jbkBgs96iCQ This version includes: * Inlet fixing holes suitable for standard 92mm fans * Outlet fixing holes suitable for standard 40mm fans In this version, I have made the following improvements: * A standard outlet fixing plate designed for 40mm fans * A completely new turbine geometry optimized for a 40x40mm output (true diameter: 38mm) * A deeper contact pad to ensure the impeller fits securely and nothing obstructs the turbine plane There may be more versions as I continue to refine this design with each printed prototype. Feel free to share your thoughts in the comments or ask questions - I'd love to discuss this idea and explore ways to implement it. Like to show your support!
