Flashforge creator 50mm fan mount (V2)

First of all, is there anyone whose still using FF Creator? Because I am.
Here is an upgraded fan mount.
There is nothing wrong with previous design, but I just wanted to make more efficient fan mount.
I am not sure how much improvement there would be.
Feel free to try it out and let me know.

* I have problem with printing at the end. the printer goes extremely slow at the end, and the handle on the top gets all messed up because of the heat. Does anyone know how to fix that?
