I met "Aaron Double Twotimes" when I bought my first printer (April 2011, a cough, cough thingomatic. I learned my lesson). Back then He had a PLA vase made on a "cupcake" that was H2O tight from increasing the extrusion multiplier if I remember correctly. He treated the outside too but I don't remember with what but He stressed the multiplier part as important. I tried to duplicate it but never got close.
The guy's a genius. He made a dual extruding cupcake back then!
