This is a fan bracket for the Raspberry Pi Compute Module 4. It holds a 40mm Fan and was specifically designed for a 5v Noctua fan.

However if you use the Fusion 360 file you can adjust the pole height en diameter via the parameter settings.

You also need to print some spacers, otherwise when you bolt down the bracket, the CM4 module will bend.

The fan is tightly fit onto the poles.

The bracket is, in this case, mounted to the CM4 IO board, with a 1,2mm spacer between the CM4 module and the board. I used four M2,5 x 10 pan hat screws for this.
