I made a simple holder for a 60x60x10 fan (like this one)
The mounting holes for the fan are 3.2mm and the mounting holes are 5.5mm. The distance between the fins at the bottom is about 4.8mm, so an M5x20 screw will hold the fan securely in place.
The Fusion 360 file is attached, if someone wants to modify it.
