I made this remix, as the original fan was almost impossible for me to get out of the fan holder after the fan was installed. This design uses the default screws from the original fan shroud to hold the fan in place. This lets you install and replace the fan more easily.
Thank you very much @IhorPomaransk_847141 for making the original model.
I have noticed that the model I have provided before, has had wrong geometry, as it was exported wrongly. I have edited and uploaded the correct version of the fan holder. I am sorry for the inconvenience this may have brought you.
The author remixed this model.
I added holes to the fan holder so that you can use screws to hold the fan in place instead of plastic pegs.
