Ever wanted a vase that looked like a tornado? Or a tornado that's also a vase? Well, luck smiled upon you, finally you can print one! :)I modelled it in Maya, it's designed to be easily printable, with no external support, even with 0% fill. More info here: http://zoltanb.co.uk/tips-and-tricks-on-preparing-complex-models-for-3d-printing/Go on, print one! All comments/criticism/improvements/ideas welcome! :)You can print this as hollow, but you will need a couple of solid layers so that the bottom of the vase is closed. Eg.:If you want to put water in it, try spraying the inside with varnish to seal it completely. You don't want a leaky tornado... :)
