Updated version of my square pots/planters, now with a liner, improved bottom structures, and deeper dish. Fast printing, reasonable material consumption, works great as planter for cat grass.

Print the liner in vase mode, I prefer transparent/natural filament to minimize exposure to potentially toxic pigments/other additives, food-safe materials would be ideal. The liner is sized to be slightly shorter than the pot, which also allows a second liner to be placed inverted on top to form a mini greenhouse for seed germination.
