Remixed version of this design which removes the weird seam on one side, that's all.
To improve buoyancy, you could vary the infill density as follows (works on PrusaSlicer and SuperSlicer, but I'm sure it will work on other slicers as well):
This should remove some weight from the object, useful if you are going to put large seeds in it.
Printing with filaments that don't absorve water is preferable, like PETG.
