Renkforce RF100 fan duct

###Size Thing size is 77 x 40 x 10 mm. ###Summary This modified fan duct, based on Oliver_D's proposal, boasts significant improvements. Key modifications include: * Air flow now follows Bezier-based shapes to enhance air flow dynamics. * Output is single-sided, aiming to boost air speed and facilitate cooling. The design remains largely faithful to the original by Oliver_D, with a few notable enhancements: * The upper-front hole has been widened to ease screw insertion, as the fan screw hole often misaligns with the radiator blade. Bending the blade slightly resolves this issue. * A useful observation: the two long screws are inserted at the bottom of the fan for easy identification when unmounting. * For detailed usage instructions, refer to Oliver_D's original explanation. ###Test Comparative 3DBenchy results: Left: Unmodified RF100. Middle: Original circular fan duct. Right: Modified fan duct with Bezier-based shapes. This design significantly improves the lower half of 3DBenchy, enhances readability of the bottom surface, and slightly improves top surfaces. While still not perfect, this affordable printer with PLA produces remarkable results. ###To be improved Future refinements: * A small chamfer should be added to facilitate seamless fitting at the radiator's bottom. * The angle may be adjusted to blow air slightly lower, as current temperature fluctuations persist (printing rafts at 205°C, temperatures briefly dip to 190°C before stabilizing).
