Object wrinkly

Hi guys,

when I send objects to the printer with spherical surface, I have this result, someone can help me ?
I tried change the temperature,adjust de bed, and the result is the same.
I'm using PLA,the brend 3d machine.(sorry for my english)

Post up the STL file. That's so far from spherical, I have no idea what I'm looking at, or what it's supposed to be.
