To be true, this vase was just a byproduct of another project, but I thought it was interesting enough to put it out there. By now I use one to store loose dice and another for descicant bags. ;)
A few things to keep in mind: the net versions are basically an exaggerated retraction test and you might end up with a clogged nozzle if you don't get that right.
The free standing version might be a bit challenging for the first 4 cm (until everything is connected). 
And: Blender would always crash when I tried to do a boolean operation on the solid versions, which is why those have an unnecessary big file size (this has no effect on the sliced result, though).
