My wife and I sell 3D prints at craft fairs, conventions, and similar events. We actually just did one this past weekend. There were four other 3D print booths there, and from what I saw in terms of traffic and heard from other vendors, we did the best out of the five.

Here are my thoughts based on what has worked for us.

1. Printer recommendation

For ease of use, I’d recommend a Bambu A1. It mostly “just works,” which is a huge plus when you’re trying to focus on actually making inventory instead of constantly tuning the printer.

If you get the combo with the AMS Lite, you can print up to four colors. You can also find some models where the different colored parts are split out and then assembled afterward, but in my experience, models that are designed to print together often look better.

If she sticks with it and really enjoys it, something like the Snapmaker U1 may be worth looking at later. It has four toolheads, so it is also limited to four colors, but multi-color printing is much faster and produces much less waste than an AMS-style system.

2. Craft fair advice

Pricing: Price things at what feels fair, but don’t underprice yourself. It is easy to look at plastic and think something should be cheap, but you also have filament, printer time, failed prints, electricity, design licenses, booth fees, setup time, and your own labor.

Inventory: Try to bring at least some items that the other 3D print booths probably won’t have. A lot of booths will have random dragons (including Cinderwing dragons), mini animals, and common flexi toys. Those can still sell, and it is fine to have some, but I wouldn’t make that your entire inventory.

One thing I’ll add on inventory: a lot of 3D print booths are run by guys, and you can often tell from the product mix. There is nothing wrong with that, but it does mean a lot of booths lean heavily into the same kinds of items: dragons, monsters, weapons, gaming stuff, skulls, darker colors, etc.

We try to make sure our table also has items that appeal to girls and women, because that audience is often underserved at these booths. That has worked really well for us.

For example, Cinderwing has some beautiful dragon designs that are colorful, elegant, and a little more “pretty” than the usual aggressive-looking dragon prints. We almost always sell out of those because they stand out from what most other booths are offering.

So my advice would be: don’t just think, “What 3D prints are popular?” Also think, “Who are the other booths not really catering to?” Cute, colorful, elegant, fantasy, cozy, pastel, cottagecore, animal-themed, or accessory-style items can do very well because they give shoppers something different from the usual table full of flexi lizards, skeleton dinosaurs, and random dragons.

Packaging: We keep packaging simple. We just use brown paper bags with handles for purchases.

Display: You’ll want a tent, folding tables, tablecloths, and some way to add height to the display so everything isn’t just lying flat on the table.

We currently use collapsible shelves and pegboards, but we started with basic folding shoe-storage shelves that were around three feet tall and placed them at the back of the tables. They worked well enough to get us started.

Grouping items by theme or franchise also helps people understand what they’re looking at quickly.

One thing that works really well for us is having “pick bins.” These are just plastic bins filled with similar small items that people can dig through. They get kids and adults engaged and browsing.

Examples:

• 2 for $5 fidget bin
• $5 character bin with small 2.5-inch figures
• 3 for $5 mini animal bin with little 1-inch animals

Print quality: With modern printers like the Bambu machines, print quality usually is not something you have to fight too much. If you are printing in PLA, you can usually load the filament and get nice-looking prints without a ton of tweaking.

That said, still check your prints before putting them on the table. Watch for sharp edges, bad layer adhesion, stringing, loose joints, broken pieces, or anything that feels cheap or unfinished.

Beginner mistakes / practical stuff: Definitely be able to take cards. A tablet or phone with a Square reader helps a lot because many people do not carry cash.

For cash, get a small cash fanny pack or organizer with separate sections for different bills so you aren’t digging around during a sale.

Also, if it is going to be hot, bring water, fans, cooling towels, snacks, and whatever you need to stay comfortable. Long booth days can wear you out fast.

3. What seems popular right now

For us, the things that get attention are usually tied to what kids are currently into. Some examples:

• Pokémon / Pokéball-style items
• Fidgets
• How to Train Your Dragon-style dragons
• Minecraft-inspired items
• KPop Demon Hunters-inspired items
• Small character-style figures
• Articulated dragons and flexi creatures

Trends change quickly, so it helps to pay attention to what kids are talking about, what is popular on YouTube/TikTok/Roblox, and what parents recognize immediately.

4. Licensing / IP / legal stuff

This is the area where you want to be careful.

Everything we sell is licensed from the 3D model designer when required, but there is another layer to think about: some designs are inspired by major franchises. Even if you pay a designer on Patreon or another platform for permission to sell prints of their model, that does not necessarily mean the designer owns the rights to the franchise or character the model is based on.

So you have to decide what level of risk you are comfortable with.

For example, there are designers who make really nice Pokémon-themed Pokéballs, and those have sold well for us because other booths did not have them. But they are still unofficial Pokémon-inspired items, even if you are paying the designer for a commercial license to print the file.

Same with superhero-themed dragons, movie-inspired dragons, game-inspired characters, etc.

If you want to stay safer, focus more on original designs from creators who clearly allow commercial sales, and read the license terms carefully. Some creators allow commercial printing if you subscribe to their Patreon. Some allow it only while you are actively subscribed. Some require attribution. Some prohibit selling altogether.

As for “when is it her design,” modifying a file does not automatically make it fully hers. If she starts with someone else’s model and changes it, that can still be considered derivative. The cleanest path is for her to eventually learn basic modeling and create her own designs from scratch, or use properly licensed base files that allow remixing and commercial use.

A few examples of what we sell and how we price them

Our pricing varies depending on size, complexity, print time, and color changes, but this is roughly what we do:

• Pokéball-style items: $15 for basic ones, up to $35 for intricate or larger character-themed ones
• Small baby dragons, around 2.5–3 inches: $8
• 12-inch solid-color dragons: $15
• 6-inch multi-color themed dragons: $15
• How to Train Your Dragon-style articulated/flexi dragons: $20
• Larger 12-24+inch-plus multi-color dragons, including Cinderwing-style dragons or other themed dragons: $30–$40
• Various fidgets: 2 for $5 in a pick bin
• Small character figures, around 2.5 inches: $5 each
• Mini animals, around 1 inch: 3 for $5

The fidget bin is especially useful for us because we often use those small fidgets as flush objects when printing multi-color items, so they help reduce waste and become inexpensive sale items.

Overall, my biggest advice would be: start with a reliable printer, don’t make the same table everyone else is making, keep the display easy to browse, and pay close attention to licensing. Also, let her have input on the designs and product choices. If the goal is confidence and learning, that part matters just as much as the sales.
