That probably isn't the model to get either for clean prints either. While that version looks cool, that design is probably not as accurate as something like a Makerbot or one of the newer Reprap models. I remeber seeing people making this design about a year ago, think they called it a Rostock.…
Amazing invention! This is the kind of 3D printing where you can show off your true craftsmanship. Anyway, I wonder what type of plastic filament you can use for this. Does it support any of these types of filaments? http://www.3d2print.net/shop/filament/. Id like to try the Nylon filament here.
