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

This is the third iteration of my fan-upgrade project, which involves a 3D printed upgrade for an old 80*25mm fan. If you print this case, please contact me or share your experience. The goal of this project is to give new life to an old noisy 80mm fan commonly used in computers and similar devices. To install the upgrade, cut the central holding plate (motor legs) from your old fan and attach it to the central pad of the 3D printed body using double-sided adhesive foam or flexible glue. The foam/glue will help absorb fan vibrations, resulting in a silent turbine blower for your projects. This version features standard outlet fixing holes, such as for a 40mm fan, and a new turbine geometry designed for a 40x40mm output (with an actual diameter of 38mm). The contact pad has also been deepened to ensure the entire impeller fits within the turbine plane. In future versions, I plan to print the fan upgrade in two parts, placing each onto the external side of the total body to avoid negative corners in the walls. After printing, use superglue or acetone (for ABS) to join the parts together. Finally, attach a cooler using double-sided foam adhesive or other "soft" glue, such as silicone. I welcome your thoughts and questions about this idea and its implementation. You can find a Thingiverse mirror of this project at https://www.thingiverse.com/thing:2560726.
