You pay by the gram (starting at 50cents), and there is an FAQ on the wall:
If anyone know of other libraries with makerspaces, please let me know. I'd love to learn more about these places and see what types of machines they have. I imagine a lasercutter would be pretty useful, along with a digital photography station. Library makerspaces are totally awesome and cool! I'm going to have to come back some day to try it out.
