Hmm, never thought about that. I will have to try to find a guitar string that is the right size for the nozzle.

Oh okay, makes sense. I changed out the nozzle, but haven't got a chance to try it out yet. I did find out though that the plastic extruder pieces I printed off a few weeks ago were the cause of problem I believe. They weren't causing enough bite on the filament to push it through the nozzle.
