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

thingiverse

This thing is a nice add-on for everybody that likes to print with high accelerations. Everybody knows that the standard cooling fans 5015 likes to rattle like crazy if you print with high acceleration. This is a simple clip that holds the fan blade against its bearing so it does not move when the printer changes direction or stops. It is designed as a two part clip that fits around a standard 5015 fan. Needed non printable parts are: 1x M3x4mm screw 1x M3x6mm screw with pointy tip a tiny bit of grease The screw with pointy tip is used to lightly press against the center of the fan blade. You can use any standard screw and grind a pointy tip yourself. Make sure to align the clip right. The pointy screw needs to press against the dead center of the fan blade. Adjust the center screw to a point where its just touching the fan blade. I find it easy to set the fan to a really slow speed and adjust the screw that there is a minimal speed change, just enough to be noticeable. This ensures the screw is only touching with very light force. As a last step you can add a little bit of grease to the fan blade where it touches the screw, to reduce the wear on the fan blade. Print the part without support on the flat side with the arms standing upright. 0.2 layer hight works fine
