Dear 3D masters,

Please my photos. As a new owner of member of 3D community I'm making my first steps towards good prints.

I've decided to start with upgrades like bed support and etc.. First i've printed the back plates for bed supports and they've came out not bad at all. But now i'm stuck with support arms...

First good print of support arm went bad somewhere 30% in to the process... I think that one side of the print separated from the bed and printer's nozzle started hitting it.
I've tried fiddling with settings and such but i'm still having issues. What can be the reason for what you see on those pictures?
