<p>This is improved remix of <a href="https://www.thingiverse.com/thing:4251317">https://www.thingiverse.com/thing:4251317</a> = cutted out useless centre and fixed the height of the inner fins (rungs).</p> <p>Faster printing time about 15 %! Using less material and less supports (only touching buildplate)</p> <p>I measured noise reduction about 7 db!</p> <p>Compatible with Ender 3 and similar printers (60 mm fan) - Alfawise U30, Alfawise U30 Pro, Longer LK4, Longer LK4 Pro, Geeetech A10, ...</p> <p>INSTALLATION NOTE (by Jimbo_Jones_): A word of advice for the installation. Remove only one screw at a time, starting with the upper left one then rotating the duct up so that you can access the second screw. Otherwise the fan will fall into the power supply. The two sections where the screws go in are quite thin, this is to make sure you have enough thread on the existing screws to install the cover (no need for new screws!).</p> <p>Check also my fan silencer for cpu/motherboard fan: <a href="https://www.prusaprinters.org/prints/44687-cpuboard-fan-silencer-ender-3">https://www.prusaprinters.org/prints/44687-cpuboard-fan-silencer-ender-3</a></p> <p>Please share your makes and send me your thoughts about this thing!</p> <h3>Print instructions</h3><p>Print it on its top side down<br/> Support: touching buildplate<br/> Infill: 15%.</p>
