Plant Watering Bulb for Vase Mode

Running low on my first spool of filament, I wanted to create a watering bulb that would do the job with very little plastic, and print quickly enough for a small garden. Ideally, a vase mode print. I designed this watering bulb to be watertight when printed with vase mode, so I tried to stay away from steep curves. This is why this bulb has a distinct low-poly, keeping the layers not too steep.

I designed this in 3DS Max because I know it more than any other software.
