I designed a couple vases the other day. I've only printed one, the Large Vase (due to large filament cost). The others I'm pretty sure will work... just make sure to have a thick shell.

Not all these are watertight. NW signifies that it is not watertight, while W signifies that it is.

I printed this on a large printer. I would recommend something with about 300x300x400 mm build size... that's what my CR10 has. If you don't have that size, you can probably cut the file into a bunch of smaller pieces (I would use Maya, but I think most 3D modeling programs will be able to do this relatively straightforwardly).

If you have any questions, comments, concerns, or requests for another design, please comment. Happy printing!
