Sturdy Aerogarden seed pods

I was not satisfied with other seed pod designs for Aerogarden, so I designed my own. The spiral structure is designed to be sturdy for printing without any supports - very low risk of spaghetti as it prints. It fits these seed starter sponges available on Amazon, and works with existing grow domes.

I recommend you print these with PLA using just 1 vertical shell and 10% infill; extra shells or infill just waste time and filament. To be extra careful with food safety, I use a stainless steel nozzle and natural (uncolored) filament.
