Vortex Vase (with flat bottom)

Remix of: http://www.thingiverse.com/thing:128021

The floor of the original vase is rounded upwards, which not only causes printing problems, but makes it difficult to use it as a tealight holder because you'd have to balance the tealight in the middle.

I simply removed the entire bottom of the vase, and replaced it with a thin cylinder -- flat on both sides.

Update: I failed miserably at printing it, anyway! I guess I need some supports at the top...
