<p>Edit5: Added a version with indentations to fit these magnets: <a href="https://www.amazon.fr/gp/product/B07VLFWB6X?">https://www.amazon.fr/gp/product/B07VLFWB6X</a> (Thickness measurement is without glue tape).</p><p>Edit4: Added the lid in one piece. Also fits the Sovol SV03.</p><p>Edit3: Changed the outer holes to slots for a better fit to all sides of the printer case.</p><p>Edit2: Increased the tolerance of the snap fit from 0.2 to 0.3mm since one person reported it's a very tight fit.</p><p>Edit1: Updated the files, added bigger and more ventilation slots to allow for better air circulation.</p><p>The SV01 is a great printer but for me its fans are way too loud. This is why I made a cover with 2 holes (+4 fan screw holes) and installed 2x 120mm NF-S12A ULN Noctua fans.</p><p>This is my very fist design, I made it with freecad, so don't expect it to be perfect. All I can say is, I printed it and it fits.</p><p>Ok, most important think first: If you plan on using this you'll have to exchange the stock rubber feet of the printer for higher ones! YOUR PRINTER WILL GET HIGHER, FOR AT LEAST 3CM!<br>I used 75mm high doorstops as new feet. You could get away with 60mm ones (the stock ones are roughly 30mm high) to maintain the same distance from cover/lid to the ground.</p><p>Here's the whole parts list:<br>4x 75mm rubber feet (I used doorstops): <a href="https://www.hornbach.at/shop/Tuerstopper-Deltafix-schwarz-40-x-H-75-mm/8450410/artikel.html">https://www.hornbach.at/shop/Tuerstopper-Deltafix-schwarz-40-x-H-75-mm/8450410/artikel.html</a><br>8x M4x35mm screws + M4 nuts for the fans<br>2x 120x30mm fans (I used Noctua ultra low noise fans): <a href="https://www.amazon.de/Noctua-NF-S12A-Geh%C3%A4usel%C3%BCfter-120mm-braun/dp/B00BG23S28/?">https://www.amazon.de/Noctua-NF-S12A-Geh%C3%A4usel%C3%BCfter-120mm-braun/dp/B00BG23S28/</a><br>1 step down/buck converter + XH2 or PH2 JST connectors and others of your coosing (dupont for example)</p><p>The parts snap together, concerning the fans for the new mainboard fan I used a "alway on" fan port on the motherboard, next to the hotend fan connector. Since the 12V fans don't like 24V you'll need to put a step down/buck converter in between.<br>I completely removed the cover of the PSU, the PSU fan and the stock mainboard blower fan (which blew against a big cable bundle thus was completely useless).<br>To get to the right lid screws of the PSU you'll have to remove the 4 screws under the heatbed that hold the whole PSU in place.<br>The second 120mm fan is plugged into the PSU fan port (where you removed the stock PSU fan).<br>And that's it! Assuming you also swapped the stock hotend fan and the mainboard to a silent board, you now have a nice and quiet SV01 :)</p>
