Revision 020415: Added vase9a-half-open-2 version with thickened cage. Revision 020315: Per the request in the comments by hgcl, I have added a -2 version of the fully open vase, making the cage wire fully round. Also, I added some supports under the ball of the caged ball. Also added as version -2. I cannot add the supports I used in Simplify3d. You can save them separately, but they are proprietary. I do not use any support on the upper open cages. If you cannot do manual support for the bottoms, then stick the the closed bottom versions. I revised Version 9 of my vases and bowls collection from my other designs with a smoother transitions at the base and various other improvements and variations, including various levels of open sides, and a bowl with a captivated ball. I also found out that when I export .STL using facets as opposed to tolerance, the export routine was introducing defects that you will not see with the models included here here. Scale them, stretch them. Some will need support depending on your settings. The captivated ball will need some supports under the ball. Enjoy!
