What went wrong?

[BechGameplay]

Hello

I am new in the 3D printer community, and does not know a lot about 3D Printing so far.
I am currently using an Ender 3 3D Printer with PLA filament. I am using the recommended settings on Ultimaker Cura 3.4.1.

I tried to print a one-hand book reading accessory from thingyverse, and it made this weird "offset" in the layers. (Images below)
- I am not quite sure what causes this. I thought it might be bad G-Code but i am not sure.

Hopefully someone in this forum knows what went wrong.

It appears the the X-Axis belt is loose and slipped, causing the offset.

Difficult to tell with no X,Y-Axis relationship, can you post more pictures showing a larger portion of the bed.

BTW, unless you have tiny fingers, your thumb will not fit in the page holder.. You must scale it up for adult sized thumbs..
