Cog vase

I wanted to design a vase, that would visually combine the strength of massive struts with finesse of a gentle curve.

There are two versions of the model:

• cog.stl is intended to be sliced in a regular way 
• cog_vase_mode.stl needs to be sliced inVase Mode, also known as Spiralize Outer Contour mode

Easy to print, support may help with the bottom of the curve, but is not strictly necessary.
