This is a 3D printable Bulbasaur, plant pot that I designed myself, most of the ones you find are pretty much the same two files or so being resold. So I wanted to make this Bulbasaur a bit different and have it lying down, part of the reason is so you can also put taller plants in it like bamboo. I used the software Meshmixer, and this took a few days to design, so I really hope you enjoy!
If you want to make sure it's watertight, use at least 0.3mm or smaller, and at least 20% infill, and if that still doesn't work, you can put a thin layer of wood glue on the inside of the bulb and that'll do the trick! Also, the file is already transported as rather small, so you can upsize it yourself to whatever suits the size of your plant.
