If you want a real orchid to thrive, you’ll have to make the layers stronger than a paper cup, add a slight lip around each drainage channel and give the walls a bit of overhang so the first layer can sit on the second without collapsing. Print a few test sections with 0.3‑mm walls; 0.2‑mm is fine for a printer that doesn’t complain, but the 0.3‑mm gives you a safety margin for the soil weight. The trick is to hide the seams: leave a 0.5‑mm gap at the joint where the drip line meets the next layer—if you seal it tight, the water will back up like a swamp. And remember, the printer will love a small brim on the base; if you skip that, you’ll end up with a wobbling “organic” shape that’s more sculptural than functional. If you need to test, print a tiny section of the drip system alone first, then assemble. Don’t ask me for beginner tips, just a few hacks to keep the printer from misbehaving.
