New to modeling and need help to show stl in repetier.

[Art3dify]

Hello as the title states I am new to modeling so I have made a likeness of my nephew on Makehuman. I posed it in Blender and exported it as an .stl file but, when I load the .stl into Repetier it does not show up. I tried re-sizing to see if it was too small or too big to show. Is there another step I am missing? I was looking up information online and someone said they used Makehuman < Blender < Autocad to get it to .stl form to print. Do you really need to go through all these steps to make it print? Not really sure what that is about as I am a total noob to modeling. It was difficult enough to figure out how to get the pose I wanted just by playing around with it. I can't afford Autocad. Attached is the file in question. Thanks.
Never mind! I figured it out myself doing some digging I used meshlab to make it into an stl..
