If you have a 3D printer and a standard 32oz wide-mouth mason jar, you can grow your own food! How cool is that?
Just print it, put it together, place it in a location with direct sunlight and watch what happens.
Sorry about the long winded post, this is not so much about the two little STL files that you can print, but more about what the outcome could be and how to use them.
Depending on the type of vegetable you are trying to grow, the initial charge may last for the entire life-cycle of the plant, so there is zero watering required. The upper part holds the pebbles in place, is slightly slanted (like a funnel) and allows for easy re-charging if needed.
Also a neat project for kids or students.
This design suspends a standard 1.5 inch rock wool cube at the optimal height in a mason jar. This allows for starting with a maximum amount of nutrient solution.
Recommended Filament: PETG (for food safety) PLA is NOT recommended for this.
Recommended Nozzle: Stainless Steel (standard brass nozzles are said to introduce lead into the printed object and we don't want that)
