If you want a vase with a drain, the Flat Top versions will work in vase mode in PrusaSlicer.

Pointy Tops will not work with Vase Mode.

We got the pointy tops and flat tops,  with drains or solid bottoms. There is also a base plate to catch draining water. No supports needed. Inner diameter is 63mm at current scale.

I printed mine at 0.20 layer height with a 0.60 nozzle. I highly recommend tricolor silk pla, it really pops on these.

The multicolor ones we're both printed with YOUSU PLA Tri-Color Red/Gold/Blue.

Vase Mode Scaling

For some reason when scaling this model in vase mode at certain percentage ranges the slicers go derp with random corners creating horizontal line breaks in the print. In Prusaslicer this can easily be resolved by scaling the model first, and then selecting the ‘Fix through the netfab’ option. 

Scale > Repair through the netfab

Edit: Added a taller version for a request. It looked okay when I sliced it, but no guarantees, especially for vase mode.
