120mm PCI slot fan duct

This is a simple fan mount/duct that takes up approx 3 PCI slots and provides a duct for a 120mm fan. Attach the fan thru the holes using zip-ties. Note that it may impede on the 4th PCI slot some, but it will fit okay if it's something that isn't too big. Mine co-exists with a serial-backplate in the next PCI slot.

This part has support built in which I think should be sufficient on most printers. It should be printed with the large, flat "bottom" facing down as shown with the purple ren
