A globe shaped container, intended to be printed in spiral/vase mode.
You may want to stop your print before completion to make a wider opening at the top.
The scale on the STL file is tiny so you'll probably want to enlarge it in your slicer software.
I scaled my print to a height of 150 mm
The initial STL was generated in Octave, then with Blender I added a top and a bottom to make the shape a proper manifold.
