Avocado Seed float for starting in a 2 Liter bottle

Just wanted something simple to start a couple of Avocado seeds growing. I had some 2 liter bottles to cut up and this is what I came up with. The "boat" fits inside the bottle with room all the way around. The only thing I had to do after printing was spray paint the boat with enamel or epoxy in order to seal it. Oh, I also set the in fill to 4% so as to make them lighter than a normal print.

Added a small optional insert so that it could be used for smaller seeds as I get to try such in
