I love the Julia Vases by @virtox, and I wanted to try my hand at
making my own fractal vase. I used an easier fractal, because my
Rhinoceros modeling skills aren't up to par yet.

NOTE!!!:
The file "Koch_Snowflake_Vase.stl" will show up in your slicer as a
solid figure. Using slic3r, I took off the top horizontal layers and set
it to 0 infill. This is the only way to make it (cleanly) into a vase.

I have included the .3dm file in case you wish to add another step in
the fractal process.
