StarTech dual 3.5 HDD Raid to 120mm external fan ducted conversion

thingiverse

I got a raid box with decent performance but the puny fan in the back was way too loud so I replaced it with a quiet 120mm fan that I just happened to have lying around. The two pieces fit together seamlessly, making printing a breeze and allowing easy access to controls and ports through the curved duct. I glued the two parts together and secured them to the top of the case using double-stick tape. The bridging of the top and bottom arches on the duct printed out perfectly without any supports needed. I happened to use a high-quality PLA+ filament that worked like a charm.
