5 Cool Things to 3D Print and Sell Online
Hey there, makers and entrepreneurs! If you’re diving into the world of 3D printing, you’ve probably already realized it’s not just a hobby—it’s a goldmine for side hustles. With platforms like Etsy, eBay, and Shopify making it easier than ever to sell digital designs or printed goods online, why not turn your filament-spinning skills into cold, hard cash? In this post, we’re exploring five cool things you can 3D print and sell online. We’ll break down each idea with practical tips, design considerations, and market insights to help you get started. Whether you’re a newbie with a basic FDM printer or a pro wielding a resin beast, these projects are accessible, profitable, and downright fun.
Before we jump in, a quick note: Success in 3D printed sales comes down to quality, uniqueness, and marketing. Source your filaments wisely (PLA for affordability, PETG for durability), and always check for copyrights—original designs are key. Let’s print some money!
1. Customizable Phone Stands
Phone stands are the unsung heroes of everyday life. In a world glued to screens, everyone needs a reliable way to prop up their device for video calls, streaming, or hands-free navigation. 3D printed phone stands are a hot seller because they’re cheap to produce, highly customizable, and solve a universal problem. You can print one in under an hour with basic PLA filament, and prices on Etsy range from $10 to $25 depending on complexity.
Why sell them? The market is booming—global smartphone usage is over 6 billion, and with remote work here to stay, demand for ergonomic accessories is skyrocketing. Personalization is your edge: Offer options for engravings like names, logos, or even astrological signs. Use free software like Tinkercad to tweak designs, or grab open-source models from Thingiverse and remix them.
Design Tips
- Adjustable Angles: Incorporate hinges or slots for 30-90 degree tilts to fit different uses.
- Material Choices: PLA for vibrant colors; ABS for heat resistance if near laptops.
- Size Variations: Standard for phones, larger for tablets—cater to iPhone and Android crowds.
Production-wise, batch print multiples on your printer’s bed to save time. A single Ender 3 can churn out 5-10 stands per run. For selling, high-quality photos are crucial—show them in action with real phones. Target niches like gamers (with controller holders) or office workers (with cable management). Potential earnings? Sell 20 a month at $15 each, and you’re looking at $300 profit after materials.
Challenges include competition, so differentiate with themes: Eco-friendly stands from recycled filament or glow-in-the-dark versions for night owls. Legal tip: Avoid branded designs like Apple logos to steer clear of IP issues.
Market Stats Table
| Platform | Average Price | Monthly Searches | Competition Level |
|---|---|---|---|
| Etsy | $12-20 | 15,000+ | Medium |
| eBay | $8-15 | 10,000+ | High |
| Amazon Handmade | $15-25 | 20,000+ | Low |
Overall, phone stands are a low-risk entry point. Start small, gather reviews, and scale up.
2. Personalized Keychains
Keychains might seem basic, but in the 3D printing realm, they’re a customizable cash cow. Think beyond the boring acrylic tags—print intricate shapes like mini sculptures, zodiac symbols, or even functional multi-tools. These tiny treasures cost pennies to make (under $1 in filament) and sell for $5-15, making them impulse buys at markets or online.
The appeal? Sentimentality. People love gifting personalized items for birthdays, weddings, or holidays. With 3D printing, you can offer text engraving, shape customization, or even embed LED lights for a premium twist. The global keychain market is worth millions, and handmade, unique pieces stand out against mass-produced junk.
Customization Ideas
- Text and Shapes: Names, initials, or pet silhouettes—use Fusion 360 for precise engraving.
- Themed Collections: Holiday specials like Halloween pumpkins or Christmas ornaments that double as keychains.
- Functional Add-Ons: Bottle openers or USB drives integrated into the design.
Printing is straightforward: High-resolution settings (0.1mm layer height) ensure crisp details. Resin printers shine here for smooth finishes, but FDM works with post-processing like sanding. Sell on Etsy with bundles—buy three, get a free chain. Marketing hack: Use Instagram Reels showing the print process to build hype.
Profit potential is high; low material costs mean 80% margins. Watch for trends: Pop culture references (non-copyrighted) like superhero motifs can boost sales during movie releases. One seller reported $1,000/month from seasonal keychains alone.
Sales Channel Comparison Table
| Channel | Pros | Cons | Best For |
|---|---|---|---|
| Etsy | Built-in audience for handmade | Fees (6.5% + processing) | Custom orders |
| Personal Shopify Store | Full control, branding | Marketing required | Bulk sales |
| Faire (Wholesale) | Access to retailers | Minimum orders | Scaling up |
Keychains are perfect for beginners—quick prints, endless variety, and easy shipping.
3. Desk Organizers
In the era of home offices and cluttered workspaces, desk organizers are more than functional—they’re sanity savers. 3D print modular trays, pen holders, or cable clips that snap together like LEGO. These mid-sized prints (2-4 hours each) fetch $20-50 online, appealing to professionals, students, and gamers alike.
Why the demand? The rise of WFH has exploded the market for office gadgets; Statista reports office supply sales up 15% post-pandemic. Customizable organizers let buyers match their aesthetic—minimalist, steampunk, or colorful. They’re also eco-friendly if printed with biodegradable PLA.
Design focus: Modularity is king. Create interlocking pieces for expandable storage. Tools like Blender help with organic shapes, while OpenSCAD suits parametric designs that auto-adjust sizes.
Build Features
- Compartments: Divided sections for pens, notes, and chargers.
- Mounting Options: Wall-hangable or desk-edge clips for space efficiency.
- Finishes: Painted or wood-filled filament for premium looks.
Production tip: Print in batches with rafts for stability on larger bases. For selling, emphasize durability—test with heavy loads. Platforms like Amazon Handmade love these for their practicality. Niche down: Organizers for specific hobbies, like artist palettes or mechanic tool trays.
Challenges? Shipping bulkier items ups costs, so offer digital STL files for $5-10 as a passive income stream. Successful sellers hit $2,000/month by bundling sets.
Material Cost Breakdown Table
| Material | Cost per Organizer | Print Time | Durability Rating |
|---|---|---|---|
| PLA | $0.50 | 2-3 hours | Good for light use |
| PETG | $0.80 | 3-4 hours | Excellent, flexible |
| Resin | $1.20 | 1-2 hours | High detail, brittle |
Desk organizers blend utility and creativity—ideal for building a loyal customer base.
4. Miniature Figurines
Who doesn’t love a tiny collectible? 3D printed miniatures—think D&D characters, animal sculptures, or pop culture homages—are a geek’s dream and a seller’s delight. These detailed prints sell for $15-40 each, tapping into the $10 billion tabletop gaming industry.
The magic? Resin printing unlocks insane detail for scales like 28mm heroes. Even FDM can work with supports for larger figs. Customization reigns: Poseable limbs or painted finishes add value. Fandoms drive sales—Warhammer, Pokémon-inspired (original twists only), or custom pet portraits.
Printing Pro Tips
- Supports and Orientation: Print upright with tree supports to minimize cleanup.
- Post-Processing: Sand, prime, and paint for pro results—boosts perceived value.
- Series Building: Create themed sets for higher average order values.
Market via Reddit’s r/3Dprinting or gaming forums. Etsy listings with assembly videos convert well. Profit margins shine at 70% after paints. One creator cleared $5,000 in a month from a viral elf series.
Risks: IP infringement—stick to originals. Start with free models from MyMiniFactory, then design your own in ZBrush.

Sell on Etsy with lifestyle shots—models wearing them at events. Pair with earring backs or chains (source cheaply). Margins? 60-80% after plating. Trend: Eco-jewelry with plant-based resins draws conscious buyers.
Challenges: Durability testing—drop tests ensure quality. Digital sales of designs add revenue without shipping.
