Saving part as .STL

Hi everyone,

Im a mechanical engineering student and we use the 2011 student version kit for our solidworks projects.

I want to get an estimate on 3d printing for some parts but I cant save the files as .STL in this student version.

I was wondering if I can use your help, and save the files in the required format? ;-)

Files attached.

Thanks !
