Seedlings Pot Add-ons

Love this design, but wanted to be able to refill the bottle without making a mess. Print the plug in a food safe hard plastic and the ring in a flexible like TPU. Put the ring on the plug, then put the plug in the mouth of the bottle. Now, when you turn the bottle over the plug stops the water flow until it's screwed into the base. For the ring, I recommend printing in TPU with 1 perimeter and no infill. It needs to be soft.

I also wanted to be able to easily get the seedlings out of the pots, so I added a pot with a hole in the bottom and a push-up disc. Just drop the disc in the bottom of the pot, then put in your soil and seed. When the seedling is ready, push up on the disc from underneath with your finger to remove the plant.
