Printed this on my A1 but it will also print on any other Bambu Lab printer such as the P1 or X1 and A1 Mini.

I printed this in BL PETG CF Black. Supports are enabled.

This is an aux fan mount adapter to install a 92mm fan into a PCIe slot.  The nice thing about this fan mount is that it doesn't require screws, we simply flex the adapter around the fan and it stays in place snuggly via friction.  Don't be afraid to really jam the fan into the adapter card, it requires a little muscle to get it into the adapter for a tight fit.

This design model was created by ChrisDaley007 - “92mm GPU Cooling fan mount” https://www.thingiverse.com/thing:3168829

I'm using this in my server to install a 92mm noctua fan and cool the memory DIMMs in the back of the case near the 2nd CPU socket. Those memory slots do not get very much active cooling in the back of the case without this fan mount.
