22mm Fan Frame for Noctua A12x25 (FormD T1)

prusaprinters

<p>This model is based on <a href="https://smallformfactor.net/forum/threads/noctua-nf-a12x25-22-mm-3d-printed-frame-with-magnetic-pogo-pins.16442/">eedev's fan frame</a> with the pogo pins on the side. In my case i didn't need the cutouts for the pogo pins as I was using the original cables and it was harder to print with supports in PETG. So I removed the cutouts, changed the wiring tray and made the inner hole diameter 11mm, which is perfect for pressure fitting the fans.</p><p>So here is what you do (also check photos):</p><ol><li>Grab some pincers like the blue ones that come with many 3d printers and cut the 4 struts of the frame</li><li>Now you need to cut all material around the brass pin to eventually remove all material around it (Take your time on this one and watch out to not damage the pcb)</li><li>If you successfully removed all material and the brass pin lays free you can fit it in your new 3d printed frame</li></ol><p>I used these <a href="https://www.zollshop.de/de/Zollschrauben-UNC-No.-1-12/No.-1-12-UNC-Linsenkopfschrauben-mit-Innensechskant-verzinkt/No.-6-32-UNC-Linsenkopf-verzinkt/3186/6-32-UNC-x-5/16-Zoll-Laenge-7-93-mm-Linsenkopfschraube-verzinkt/">screws</a> to secure the fans to the radiator, but i'll add a model which works with the standard 6-32 screws, which come with most rads soon.</p>
