CR-10s Pro Main Board Fan - 40x40x20mm

I'm going to modify the fan to fit within a 40x40x20mm space. The original design can be found at https://www.thingiverse.com/thing:3399705. However, I've noticed that the two mounting screws for the fan require M3 threaded holes. When printing with a resolution of 0.2mm, these threads often turn out rough and may need some force to secure them initially. Despite this, they do become slightly easier to install over time. A FreeCAD design file is included for your reference.
