A seed starter for 36mm peat pellets for hydroponics.
Remixed to fit on a Prusa Mini sized bed.
I printed mine in PETG because it spends time in the greenhouse. PLA will likely work for indoor only setups, though if you use a seed starting heat map your mileage may vary.
The author remixed this model.
I removed some space between each of the cells and the water reservoir is a little smaller.
