Help to convert a solidworks file to stl

Hi

I have a solidworks file that I would really like to 3D print for a project but I can't convert the file as I do not have solid works yet,

the file was obtained from a public file sharing site for 3D printing enthusiasts but was in the wrong format.

I was hoping to print this tonight and would gratefully appreciate any help.

I have attached the file in case this helps at all 

Thanks

Ben
