extruder motor cooler duct for mk3s+

prusaprinters

<p>for MK3S+<br>Extruder motor cooler duct that is connected to the fs_cover and that simply screws on.</p><p>sadly needs supports under the fs-cover (but non under the rest)</p><p>&nbsp;</p><p>It requires a fan with 40mm diameter.</p><p>I advise a 5V fan with 2 cables. (3 cables are ok. But you can only connect two)</p><p>you need to connect the black and red cable to the black and red cable to the 40mm noctua fan cables.</p><p>If you peel of the sticker from the noctua fan, there should be exposed soldering beeds. If you are experienced in soldering you can solder the red and black cable from the new fan to the noctua fan cable.</p><p>By doing this the motor cooling fan only turns if the hotend is higher than 50°C</p><p>I printed it in green ASA and painted a bit Aceton on the support lines to make them invisible.</p>
