Fan Noise Stop (anti-vibration / rattle) 5015 Fan

thingiverse

Everybody who likes to print at high accelerations will appreciate this handy add-on. High acceleration printing can be brutal on standard cooling fans like 5015, which tend to rattle loudly as they change direction or stop. This simple clip keeps the fan blade securely fastened against its bearing, preventing any movement during sudden printer changes or stops. The design features a two-part clip that fits snugly around a standard 5015 fan. To assemble it, you'll need a few non-printable parts: 1x M3x4mm screw 1x M3x6mm screw with a pointed tip (or you can grind a pointy tip on a standard screw) A tiny amount of grease The pointed screw is used to gently press against the center of the fan blade. Make sure it's aligned correctly, as it needs to press directly into the dead center of the fan blade. Adjust the central screw until it just touches the fan blade. For an easy setup, print the fan at a very slow speed and adjust the screw until you notice a slight change in speed – just enough to be noticeable. This ensures the screw is applying minimal pressure. Finally, add a small amount of grease to the fan blade where it meets the screw, to reduce wear on the fan blade. To print the part, simply use 0.2 layer height and print without support on the flat side, with the arms standing upright.
