Vase-X1

I printed this today. It got knocked off the bed about 3 minutes before it finished. So, I created the inverted version which I will try next.
For some unknown reason Simplify 3D prints it with some slits. I can't figure it out. However, the slits are interesting.

Let me know what kind of results you get.

Added X3 version (upside-down) with thicker wall; no open slits.

Definitely print it upside-down!
The photo shows X3 and X1. X1 will have slots. X3 is thicker.
The X1 in the photo was printed right side up and decided to leave the heated bed prior to completion.
