This is the logo of the Italian Space Agency, or Agenzia Spaziale Italiana, ASI.

ASI is a government agency established in 1988 to fund, regulate and coordinate space exploration activities in Italy. ASI's main headquarters are located in Rome, Italy, and the agency also has direct control over two operational centres: the Centre for Space Geodesy (CGS) located in Matera in Italy, and its own spaceport, the Broglio Space Centre on the coastal sublittoral of Kenya, currently used only as a communications ground station.

This is part of a collection of space agency logos that I designed.

The space logos missing in my models list can be found among those by Vector3dArt and Sarusani.

I would suggest a layer height of 0.1mm and a color change at the 38th layer.
