This thing needs to be printed in 4 parts, one for each of the 4 major colors of the Google Chrome logo. Once printed, the parts screw together to make a 3D version of the logo (you can choose spherical or hemisphere version).

I've included STL files for 50 mm diameter hemisphere as well as full spherical version:

chrome--50s.stl - spherical parts
chrome--50.stl - hemi-spherical parts

Note that the spherical version needs to be printed with support.

The chrome.scad file is parameterized to make any size logo, and can optionally print a whole sphere (vs. a hemispherical version).
