Fan duct NineStars

thingiverse

The original Satsana fan duct is a good design, but it falls short in terms of optimization. In reality, the Satsana upgrade is less efficient than the original metal cube from Creality. The fan blows air directly onto the upper part of the heatsink, which doesn't effectively cool the filament inside and exacerbates stringing issues. This remix redirects the fan to blow against the heatsink, making it a more efficient design. Additionally, the holes are slightly wider for easier screw installation, and there is a small gap to accommodate wires from the fan with ease. To measure the efficiency of this upgrade, we conducted an experiment involving multiple temperature readings: from 185°C to 100°C. The results were as follows: * Creality: 1m39s * Satsana: 1m48s * NineStars: 1m18s The NineStars fan duct remix proved to be significantly more efficient, with a notable improvement over the original designs.
