Hi guys,
My prints are usually bended at one side, asymetrically.
At other forums some people are saying that it’s caused by a fan which winds only from one side. I’m using Snapmaker 2.0 350T. Could you help? All advice appreciated 
This is printed like you show in your hand.
This means you print a large overhang which causes more visible layer lines like the rest of the print.
The curling up appears because of bad cooling or printed too hot.
This comes also from very short layer times, so the previous printed plastic can’t cool down.
Have a look at this, it’s pretty the same issue:
Print a larger model or more than one piece.
Hope this helps!

Obvious questions is, why would you not print that model flat, ie. rotated 90 degrees?! It looks simple enough, based on that blurry photo, to be printed that way.

It’ll also be stronger that way.

The photo is too bad to know which way it was printed.
Those other forum people and @xchrisd are correct, this is a cooling issue.

Cool, that’s smart 
I will try. One more, do you think the position of the printing model on the bed is correct? (look at attached image)
Thank you 
Position is OK.
If you are the designer of this model, consider angles less than 50 degrees, they don’t need supports and print well.
I use a (Fase in German) chamfer for this purpose, it looks good and doesn’t need support.
I still might rotate it 90° ccw. Personally, I’d rather use supports against a flat side than a curve.
