I want to print out the venus box I've downloaded from http://www.thingiverse.com/thing:1559232
When printing the part that is called OUTDOOR, I keep getting some strange pattern that looks like under extrusion at the outer perimeter at the upper third. Even I printed the part several times, I keep getting the pattern, see the attached image below.
Interestingly to observe is that also the banding visible on the outer has a identical pattern on both prints. Print speed was set to 40mm/s.
I try now to print out the part rotated by 90° on the z-axis with a different print speed (50mm/s). Used filament: PLA at 203°C
Any guess what could be wrong?
