First of all, thank you so much for your quick answer.
The problem is with the printing result, I put the same preset that the fairphone test (same color, PLA ULTIMATE BLUE) but the result is different.
Maybe the problem is the model design because i have the feeling that the Fairphone Desighn Day 1 it´s more strait than fairphone test. I made 3 printing and i change some presets like: more quality layer (0,1mm); print speed more slowly (25mm/s); but the result it´s the same.
I let you two pictures to see the difference.
Do you know any solution?
Thank you again for all.
With kind regards,
Raphaël.

I mean that maybe the filament is thicker than the slicer thinks? E/g. when the filament is 3mm and the parameter says 2.85 mm there will be more filament extruded than you would want. In the UM2 this is in the material settings on the printer and for UM original it is at the bottom of the basic settings in Cura. In other slicers you can also change this parameter.
Ah okay, i understand what you say. In my case, the diameter parameter is the same as the filament so this cannot be but in any rate thank you for your explanation. When I receive the filament order i wil try to change some parameters and I will show you the result.
Here a custom design for the FairPhone phone case. In case you wonder what it is about: it is a logo for a Dutch political party. It is printed on a Ultimaker 2 with ColorFabb PLA/PHA filament mix, color: Traffic Red. I have a non-default fan shroud. This really makes a different.
The slicer settings were as follows:
speed: 25 mms/
layer height: 0.15
nozzle: 0.4 (the instructions in the pdf talk about 0.6 which I tried but did not deliver expected result on UM2)
temp: 215
flow: 110%
infill: 15%
I’m not sure about wheter to print no infill at all, or at 15%. (Comments appreciated on this).
When printing I print with the top overhang pointed to the right so the fan blows air straight to the overhang. So the tomato is turned to the left, and the overhang points to the right. This way the overhang gets maximum cooling, which makes all the difference. (And of course the ColorFabb filament is just gorgeous and easy to print with).
