I'm busy setting up my Makerbot, and I don't want to go out and buy a spool, so what do I do? Use the two twisty ties that came with the plastic to hang the roll from the nearest available surface of appropriate height...Every 5 minutes or so during printing you have to give the roll a turn, so this isn't a long term solution, but this will get you going long enough to print out a spool.1: Twist one tie loosely around the roll of plastic. 2: Twist one tie around your desk lamp, coat hook, or whatever you happen to have handy. 3: Twist the ends of the ties together. 4: Print away!
