So I just started learning SolidWorks in school and decided to make the N64 logo. It came out perfect and I'm looking to get it 3D printed. The 3D printer at my university requires .STl.
I installed the SW eDrawings to convert my .SLDPRT to .SLT and when I try to export it, it asks in Binary or ASCII. Are there any differences?

I looked them up and it said Binary can get pretty large, then it went into talking about colors... All I want is to get a print of my N64 logo, probably 3x3x3 inch maximum. Which is best?
