Artillery Sidewinder X1/X2 Part Cooling Fan Duct

prusaprinters

<p>This is a model based on Motogeepie's amazing design.&nbsp;<br>(https://www.thingiverse.com/thing:3927320)</p><p>After trying half a dozen of various ducts I have settled for this.<br>I have been using this duct for the past 2 years and I am very satisfied with its performance.</p><p>The original design is for the stock 4020 fan but I have modified it to suit a larger 5020 fan for a slightly better cooling performance.</p><p>The front half of the duct model (grey in the screen-shots) is intact only the back is edited to suit the larger fan.</p><p>Printing:</p><p>Front half no supports needed. Rear needs support as well as support blockers inside the air paths. I also have two pictures showing the Gcode preview so you can see where I used supports and where I haven't.&nbsp;<br>I also used draft shield as I printed this in PETG without an enclosure and certain thin parts would de-laminate without the shield.</p><p>I <strong>do not recommend</strong> printing this in PLA, it will melt because of the bed heat and the close proximity. I know this from experience. ;)</p><p>Big thanks to Motogeepie for publishing the original design in STEP format. This greatly helped me to do the modifications for the larger fan. In the same spirit I have also included a STEP file in case someone decides to do further modifications to it.</p>
