python script for printing s3g files

Here's a short python script for sending an s3g (or x3g) file to a printer via USB. Sometimes it's convenient to use MakerWare to set up a print, but then I have to walk ALL THE WAY ACROSS THE ROOM to put the SD card into our 3D printer.

I was hoping that I could save myself this exhausting physical labor by allowing an x3g file to be sent to the printer via make-me's http api, but I'm not much of a ruby hacker. Perhaps you guys can do the dirty work?

PS: It was nice meeting you guys (skalnik and thedaniel) in the restroom at Public Works :wink:
