Since the GPU in my server (a Tesla T4) was running way to hot, since it's a passive cooled GPU and I had limited space in the server (a 2 unit supermicro) - so existing adapters I found didn't fit, I came up with this adapter to fit a 60mm Noctua fan.
The GPU was hitting 96 degrees celcius before under load, now with this adapter it's “only” reaching 66 degrees celcius.
Something did go wrong with the STL export and I had to reduce the model size from a 100% to 10% in the Prusa slicer, despite the export settings being correct in mm.
The author marked this model as their own original creation.
