Weird Layer lines on 3D print

[hazza_ob]

I’m having problems getting rid of layer lines which occur every ~2mm. Although the actual lines where the layers interact are nearly invisible, these lines occur on all my prints and it’s driving me mad! (Picture below)

These are my print settings (Using PLA):

Any suggestions would be appreciated!
