You can print it in vase mode but if you want it watertight i recommend that you print it with 2 or 3 peremiters 

If you are using prusa slicer and you dont know to to put it in vase mode then her is a quick tutorial

First you need to go into the print settings and find the text “spiral vase” with a little check box 

you then need to click the little box and say yes to the window that pops up

then you just need to slice it and then you are good to go

hope you like it and happy printing ;)
