Part thickness inconsistency, walls are not adhered to each other
Hello,
I have been noticing some issues before and tried to correct it via guide for mini squaring.. Anyone has idea where to start?
here is orientation how it was printed and some measurements. It was supposed to be 2.0mm part. Printed with PLA and 0.4 nozzle. 
RE:
Can you upload the zip compressed 3mf file, to excludes issues with the model itself or your settings?

Also try to rotate it 90 degrees on the plate so it prints more along Y axis ( as opposed to current placement which prints mostly along X axis)
See my GitHub and printables.com for some 3d stuff that you may like.

Hi, thank you for your reply. Here is zipped files 3mf & stl

I will try to rotate and print it - but then if it prints fine rotated - does it mean I have issues with axis being not square?

Can't see anything wrong with the 3mf. The only meaningful modification is the default extrusion width but that's overwritten anyway by the extrusion width settings for perimeters as the model is all perimeters. What concerns me more than the size differences is the fact that you can peel the model apart in the vertical dimension, which leaves me stumped. Hard to see how axis misalignment would cause that. Feels more like a fan issue but that should affect horizontal adhesion.

This issue is noticable on majority of the prints though. Just I never had as severe as this one.
I must mention I have fan modification on my prusa mini from this post and I also use sock on my hotend: Prusa Mini RHD Front Fan Duct by bejotto | Download free STL model | Printables.com
RE: Part thickness inconsistency, walls are not adhered to each other
It may be related to the under/overextension in X axis due to Bowden tube setup. There is a thread in GitHub related to it https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/2997
For some people changing orientation on the bed is enough, for other checking Bowden tube for wear out and replacing it is enough, bit for some there is a ongoing battle in the way how printer works.

That is a good idea. Didn't think of it because my Minis have Dragon hotends so I never had to worry about it.

I have ordered new ptfe tube from extruder motor to hotend. I saw some similarity in how issue shows up to referenced post. Damn Prusa limited qty of that ptfe tube per order to 1 piece only... Paying 15 euros for one tube + delivery..ehh...

The Bowden tube I have to replace once in a while is the small one in the hot end. I have had my Mini for 5 years and never touched the long one from the extruder to the hot end.
The small one I get a few at a time, and bundle small parts with some filament to get the shipping down to a lower percentage of the sale.
Is it possible your fan mod is providing too much cooling such that the filament cools before it sticks together?
