Rack mount for server fans

DescriptionI made this model, because I wanted to cool down the rack mounted HDDs. It is still in WIP, because the fans have not arrived yet, and also the ESP32 fan controller is still not finished. The idea was that, with the middle part, it should split the air between the upper and lower set of HDDs. The real life pictures show the prototype, which has uneven distance between the fans, so I corrected it with the uploaded version.It also has a cable duct to hide the cables, and for easier management.Short DescriptionFan sizes: 40mm x 20mm or 40mm x 28mmI measured based on the dimension of the Arctic S4028 fan, but because most of these fans share the same dimension, and mostly the depth is different, it should fit most 40x20 and 40x28 fans.The prototype was printed with Sunlu 1.75mm PETG with normal snug support. It can be difficult to remove the support, so be careful with it.
