This planter stacks and holds 3 plants per level. I print it out of ASA (or ABS, then paint it).
It requires a ton of filament, but I've gotten it down to ~300g per level. I print 1 perimeter and 2 (or 3) top and bottom layers). After, I give it a coat of woodglue on the inside and paint it (if it's not ASA) for UV resistance. My lettuce are thriving in the huge space it offers.
TODO (someday) update the drain plate to catch the drain from the second level).
