Problem with Ender 3 V2 print

Hi guys,

First of, sorry for not having a specific title, but I have no clue how to address this problem. I'm new to the whole scene, and have been printing a few smaller prints over the last weeks, so I thought it was time for a bigger/longer print (https://www.thingiverse.com/thing:1311108).

The problem I'm having with this print is that the details on the side are getting fuzzy (or however you want to call it) and I can't find a solution for it. I have tried different heat/speed settings, to no avail. I am using Cura as slicer.

So, is there anyone that knows what this is called, and how to fix it? :)

Thanks in advance!

looks like you are missing supports on the edges. Those "spaghetti" hanging down is because it tried to do a bridge and it couldn't. Verify that you are using supports in the slicer.
