/diy/ - Do It Yourself

Hey guys long term /diy/ poster, but first time in this general.
Have recently purchased a 3D printer and am messing about with it. It seems to have decent performance out of the box, and I was astonished by the quality of the first print. I am printing an enclosure for an electronics project now, however I have run into some issues.
(Yes I have read the simplify3d support, it doesn't mention anything about this problem)

My printer seems to have relatively bad performance in bridging, namely a very thin stringy bridging (see the picture). I think this could probably be improved, but I was wondering if people have already had this problem and know a way to solve it. I tried messing a bit with printing speed (80% and 60%) and extrusion rates (up 10%) but none seemed to really have any impact.

I would prefer to fix this before printing the actual enclosure (what you see here is the lid) because it has more critical parts where bridging is important.

>Make & Model
Creality CR-10
>Filament type
PLA that comes with the printer
>Bed & Extruder temps
60 degr, 200 degr
>Print speed
100%, i think that is 600mm/s in Cura
>Extra info
3D software: solidworks
Slicer: Cura
In Cura I selected 30% infill with 0.2mm layer height, build plate adhesion with for the rest 'recommended' settings for the CR10.

Note that on the left side of the picture, that is support material thus irrelevant. What is mostly interesting is the fill that is going on top (that it is so thin) and the stuff marked in green.

Thanks in advance, since I am kind of at a loss.
