Most of our planters start on the back of something. A grocery list, or one memorable time the back of a discharge instruction sheet that thankfully never left the building. Caryn draws better than I do, so she draws and I say things like “the arms are wrong” until she puts the pen down.
People assume the hard part of a 3D printing business is the printing. It isn’t. We have 30+ machines in a Pennsylvania garage and they mostly just run. The hard part is everything between a drawing and a pot that a stranger will pay twelve dollars for and then not hate in six months. Here’s what that actually takes, start to finish.
Step one is an argument
Not every idea survives the kitchen table. The test we’ve landed on after eight years is simple and slightly cruel: would one of us pick this up at a show, turn it over, and want it for a specific person she already knows?
If the answer is “it’s cute,” it dies. Cute is not specific enough to print for four hours. A lot of very nice sketches are in a folder in the garage for precisely that reason, including a hedgehog I still think about.
Turning a drawing into a thing a machine understands
The model is where a good sketch goes to find out it’s impossible. A printer builds an object in stacked layers from the bottom up, which means every part of the design has to be supported by the part beneath it. Anything overhanging more than about 45 degrees from vertical either needs scaffolding printed underneath it, which then has to be snapped off and leaves a scar, or it needs redesigning so it doesn’t overhang at all.
That single constraint reshapes most designs. Ears get thicker. Arms get tucked closer to the body. A tail that swept out beautifully on paper comes back in and hugs the pot. If you’ve ever wondered why our animals all look slightly compact, that’s why. It isn’t a style choice. It’s physics with an opinion.
Wall thickness is the other early decision, and it’s a real tradeoff. Thin walls print faster and crack when somebody grips the pot too hard carrying it in from the mailbox. Thick walls survive that and add an hour to the print. We land on the heavy side of the middle.
The nursery pot decides the size, not us
Here’s the step almost nobody outside this business thinks about. A planter isn’t a sculpture with a hole in it. It’s a container that has to swallow the plastic pot a plant actually arrives in from the garden center, which in practice means a 3-inch or a 4-inch nursery pot with a rim that flares out at the top.
That flare has ruined more of our designs than any other single detail. An opening that measures correctly at the soil line can still refuse the rim, and then you’re standing at the table pushing a perfectly good pot into a perfectly good planter and neither one is wrong. Every design gets a physical fit test with three real nursery pots from three different growers, because they are not standardized and anyone who says otherwise has never measured a flat of grocery-store succulents.
Why the hole goes in before the face does
Every pot we make has a drainage hole in the bottom. That is decided at the modeling stage, not added later, because where the hole sits changes the whole base: it has to clear whatever feet or curve the design has, it has to not be the first thing that cracks, and it has to actually let water out rather than form a dimple that holds a teaspoon of it.
We are aware that a hole makes a planter slightly less convenient to sell. Sealed pots photograph better and don’t need a saucer. They also kill plants, and we’ve both spent enough of our working lives on the consequences of small preventable things to be relaxed about it.
The first print is almost always bad
A pot takes about 4 hours on the machine. So a revision cycle is half a work day, which is why we batch them overnight and find out in the morning.
Version one usually reveals something you cannot see on a screen. A curve that reads as friendly in the model reads as smug in your hand. A detail that looked crisp comes out mushy because it was smaller than the nozzle can honestly resolve. Our first booby planter had a structural flaw that we are not going to describe in detail here, and it took several rounds to fix, and version one is still on a shelf in the garage where visitors find it and ask.
Four or five versions is normal. Eight is not unheard of. Somewhere in there my husband wanders out to the garage, picks one up, says one sentence about it, and is right, which is irritating.
Color, which is not a small step
We print most designs in 14 colors, and a design has to survive all of them. A face that’s charming in white can go faintly menacing in red. Deep colors swallow shallow detail entirely, so if the expression only works in a light color, the expression isn’t deep enough yet and it goes back to the model.
Then it gets a name, because a pot with a name sells and a pot with a SKU does not. Then Caryn photographs it on the kitchen table, in daylight, against whatever surface makes the color read honestly.
And then it sits there and waits for you
This is the part that surprises people. When a design goes live, we do not print a hundred of them. We print zero.
Nothing gets made until somebody buys it. Your order lands, a machine picks it up, four hours later there is a pot in your color that did not exist that morning, and it ships within 2 business days. No warehouse, no pallet of unsold pink octopuses waiting for a November that never comes. We like to think we throw a decent pot, wheel or no wheel. It’s also why the color you pick is a real choice and not a stock lottery.
The tradeoff is honest: you wait a couple of days longer than you would for something sitting on a shelf in Ohio. What you get is a pot with your name effectively on the print queue, made from plant-based PLA, with the hole already in the bottom. Three of them come to $33 together as the Shelf Squad, which applies itself in the cart, and which exists mostly because we noticed nobody ever buys one.
Everything that made it out of that folder is in the shop. If you want the version of this story with the machines in the foreground, including what 30+ printers do to a garage in February, that’s inside our print farm. And if you want to know what all this plastic actually does to a root ball over years, we tested it and wrote it down in is PLA safe for plants.
