Yup we are up to Five (with 3 more on the way) Ender 3’s. Best little utility printer on the market IMHO.
Here are my two “honey holes” for Creality Ender 3 and CR-10 Parts.
Pretty sure they are the same people in the background.
So I print nearly continuously and one of my printers developed some vertical lines in 3D Prints. With a little research I determined the X-axis belt was a little loose. Here is the fix.

Bottom Line up front:
If you are experiencing vertical lines in your 3D Print, tighten your X and Y axis belts. This fix applies to all belt driven 3D Printers.
The Problem: Those lines aren’t suppose to be there.
This is what it is supposed to look like:
I could see when the belt was in action, there was a bit of slack when changing motion from left to right.
The fix is to loosen both Hex Cap Screws and tighten it up.
With the two screws loose, pull gently to the right and snug it up. Then tighten the screws.
To check your Y-Axis, look at how the belt rides here:
The tensioner on the front is what you will loosen, there are 4 screws here.
Pull a bit to snug it up and then retighten.
Much Mo’ Better!
