I designed this watering can for my son to go with his garden set. Most of the water cans that I saw were not functional or required multiple pieces, so I made it to be printed without supports on the Bambulab X1 and require no assembly. The "large water can" file is almost maxed on the X1's print bed. I printed it in regular PLA and it seems to be even stronger than I originally thought.

I recommend printing with 10% infill (rectilinear) and 4 walls for a better water-tight seal. You could go down to 2-3 walls to save on filament but I wanted it to hold up to a lot of toddler wear and tear. I've added internal structures into the handle and a rib inside the watering can to help support the handle and weight of the water.
