I just had a problem with the auxillary fan I printer the diffuser and now i have no clue how to fix this ugly finish.

At the bottem
I see some lines between eachother like marked on the photo.
And at the top i have some height difference.
Please let me know!

I have tried everything by now I got some good results but when I work a bit higher I get this result. Please please let me know
