3D printing isn’t just a fun hobby, it can be a side hustle or even a small business if you know what to create and where to sell it. With just a bit of creativity and the right audience, you can turn your prints into profits.

So if you are looking to make a little extra cash or your wanting 3d printing to become your main business, look no further.

In this post, I’ll walk you through cool things to 3D print and sell, plus some handy tips to help you get started.

Why 3D Printing Is Perfect for Selling

Here’s why 3D printing is such a great business idea:

• Low startup costs – once you have your printer, you just need filament and some imagination.
• Customization power – customers love personalized products, and 3D printing makes that easy.
• Rising demand – handmade marketplaces like Etsy are full of buyers searching for unique, creative items.

Think of it like this: you’re not competing with giant factories you’re offering something special that can’t be bought at Walmart.

10 Cool Things to 3D Print and Sell

Here’s the fun part! Below are tried-and-true ideas that people are already buying, plus little twists you can add to stand out.

1. Phone Stands & Holders

Everyone has a phone, and everyone needs a spot to keep it. A phone stand is practical, quick to print, and super customizable.

Create themed stands, gaming logos, animals, or even minimalistic geometric styles. These sell well on Etsy because they’re both useful and gift-worthy.

2. Custom Keychains

Small, fast, and affordable, keychains are one of the easiest ways to get started. They’re perfect for weddings, parties, or businesses that want branded giveaways.

I made a recent TikTok on how you can create your own personalized keychain, you can find that video here – How to use any font for your 3d prints.

3. Home Decor Items

Think vases, planters, wall art, or even lampshades. People love unique touches for their homes, and 3D printing lets you make eye-catching designs.

Try specialty filaments like wood, marble, or metallic PLA to make items feel more premium.

4. Jewelry & Accessories

From earrings to bracelets, 3D printed jewelry is lightweight, stylish, and trendy. You can design pieces that look modern, artsy, or even mimic expensive metals with the right filament.

Don’t just sell jewelry, sell the story behind it. A “nature-inspired” collection or a “geek chic” line will attract niche buyers.

5. Desk Organizers

In the age of remote work, desk organization products are hot. Pen holders, cable clips, and drawer dividers all sell well.

Create modular designs so customers can mix and match pieces for their workspace.

6. Pet Accessories

Pet owners spend big on their furry friends! 3D print pet name tags, food scoops, or even fun toys.

Personalization is king here. Offering engraved names on tags can make your products stand out instantly.

7. Board Game Accessories

Gamers love upgrades. Dice towers, card holders, miniature figures, and storage organizers are all great sellers.

Focus on niche communities like Dungeons & Dragons or Warhammer for repeat customers.

8. Kitchen Gadgets

Cookie cutters, bag clips, measuring spoons, and spice racks are small, useful, and fun. These are also popular during the holidays when people are in baking mode.

Bundle a few kitchen gadgets together as a “starter kit” to increase order value.

9. Cosplay & Props

This is a booming niche! From helmets and masks to detailed prop weapons, cosplayers are willing to pay for high-quality, unique items.

Offer raw prints (unfinished) and premium painted versions for different budgets.

10. Seasonal & Holiday Items

3D printing shines here! Christmas ornaments, Halloween decorations, Easter egg molds, you name it. Seasonal products are fun to make and easy to sell year after year.

Create limited editions tied to specific years (like “Christmas 2025”) for collectors.

Where to Sell Your 3D Prints

Now that you’ve got ideas, where do you actually sell them?

• Etsy – the #1 marketplace for unique, handmade items.
• eBay – great for niche products and collectibles.
• Facebook Marketplace – perfect for local sales and testing new products.
• Craft fairs & local markets – a fun way to meet customers face-to-face.
• Your own website – eventually, having your own shop (like Shopify or WooCommerce) gives you more control.

💡 Bonus: You don’t always have to sell physical items. You can also sell your digital STL files so other makers can print them. That’s passive income at its finest!

Tips for Success When Selling 3D Prints

Before you dive in, here are a few things that will help your prints fly off the (virtual) shelves:

• Quality matters – sand, paint, or smooth your prints for a professional finish.
• Great photos – natural lighting and clean backgrounds make your products look high-end.
• Offer customization – names, colors, and personal touches make buyers feel special.
• Test first – start small and see what sells before printing in bulk.
