Front Fan Mount for HDD Drive Cage in a DIY NAS Server

prusaprinters

<p>I printed the "HDD Best Rack-Adapter from 5.25" to 3.5"" by tibrol (<a href="https://www.thingiverse.com/thing:3671684">https://www.thingiverse.com/thing:3671684</a>) to convert my old PC into a NAS-Server. To attach the drives to the rack adapter I used these rails by xcvccccc: <a href="https://www.thingiverse.com/thing:3285448">https://www.thingiverse.com/thing:3285448</a></p><p>Everything fit very nicely but the drives ran too hot without a fan. So I designed a bracket to mount a 140 mm fan into the space of the four drive bezels. It fits snugly into the front panel of my case and it looks less DIY like that :-).</p><p>I put in holes for mounting the fan with heat inserts and M4 screws, but my 140 mm fan from bequiet! already has very good press fit and I did not need those. As a last step I put a dust screen in front of the fan.</p><p>This should fit into most cases with 4 5.25" bays, but I have also added the Fusion 360 file for this in case this does not fit into your case.</p><p>UPDATE 2022/3/20: Added an air guide to force the airflow from the fan through the HDD cage.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p><strong>Printer:&nbsp;</strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.2 mm</p><p><strong>Infill:&nbsp;</strong></p><blockquote><p>15%</p><p><strong>Filament:</strong> eSun PETG any</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>Only the front part needs supports from the build plate at the bottom.
