<p>Searching for a better fan duct, i found this this (thx to xander1)</p><p><a href="https://www.thingiverse.com/thing:4124587">https://www.thingiverse.com/thing:4124587</a></p><p>The initial tests weren't bad, but the airflow didn't fully reach the rear of the model.</p><p>So I copied the design and gave it a bit more length and air baffles to get more air behind the model. Thicker walls give the part a little more strength against the heat.</p><p>In addition, I added another holding element for the original fan bracket (Prusa R4 / R5 / R6 Part).</p><p>Since the PINDA holder tends to lower itself at high printing temperatures, I added a reinforced notch to support the probe.</p><p>My parts are printed from Prusament PC Carbon Fiber to withstand higher temperatures. It prints great !</p><p>I think the ASA is sufficient for normal prints with PETG and PLA.</p><p>It is best to print 3 or 4 perimeters, much infill ~50% and supports at the air outlets as shown in the picture (no supports for PC Carbon Fiber needed ! )</p><p>The fan mount could be print with PETG.</p><p>You need:<br>1x M3 Squarenut (use the existing one)<br>1x M3x8mm<br>1x M3 Nut (use the existing one)</p><p>&nbsp;</p><p><strong>FLOWSPLITTER Version added &gt;&gt; Flowsplitter: </strong><a href="https://www.prusaprinters.org/prints/124051-print-fan-flowsplitter-mk3-mk3s-mk3s-and-many-othe"><strong>https://www.prusaprinters.org/prints/124051-print-fan-flowsplitter-mk3-mk3s-mk3s-and-many-othe</strong></a></p><p>&nbsp;</p><p>Update 04.03.2021<br>added a MK3S+ Version</p><p>Update 18.08.2021<br>renamed the MK3S+ file and updated the file to the latest Iteration (only small changes for PC &nbsp;Carbon Fiber printing).</p><p>Update 11.01.2022<br>new lower version added 1.5mm deeper with or without silicon sock.<br>some new pictures PC Carbon Fiber Parts after 6 month of many printing.<br>the mk3s+ (R6) parts works on mk3s (R5) too !&nbsp;<br><br>Update 22.01.2022<br>renamed Files the “+” will be removed in downloadable zip files O_o<br>added a lowered 0.5mm and 1.0mm Version&nbsp;<br>the mk3s+ (R6) parts works on mk3s (R5) too !&nbsp;</p><p>Update 31.01.2022<br>FlowSplitter version added - Flowsplitter ?
