Free 3D Models: The Best Sites and 30 Easy Prints for Beginners
You don’t need to know 3D modeling to enjoy a 3D printer: hundreds of thousands of models are free to download. Here is where to find them, how to spot a good file, what the licenses allow, and 30 easy, useful and fun prints to start with.
Key takeaways
- The big free model sites are Printables, MakerWorld, Thingiverse and Cults. Thangs searches several sites at once.
- Models come as STL or 3MF files and go through a slicer before printing.
- “Free” does not mean “free to sell”: the license says whether you may remix the model or sell prints.
- As a beginner, pick models that other people have already printed, with photos and comments.
The best free 3D model sites
| Site | Run by | Strengths | Good to know |
|---|---|---|---|
| Printables | Prusa Research | Huge catalog, good moderation, contests and rewards for designers | Print profiles mostly target Prusa printers, but files work with any printer |
| MakerWorld | Bambu Lab | 3MF files with ready-made settings, one-click printing to Bambu Lab printers, lots of multicolor models | Downloadable for other brands too, with settings to adjust |
| Thingiverse | UltiMaker | The oldest and one of the largest catalogs, tons of practical parts and remixes | Many older models, uneven quality, dated interface |
| Cults | Independent platform | Free and paid models, many miniature and decor designers | A large part of the catalog is paid |
| MyMiniFactory | Independent platform | Strong in miniatures and tabletop gaming, many pre-supported resin files | Many models are paid or sold through designer memberships |
| Thangs | Independent platform | Search engine that finds models across several sites, search by shape | Often sends you on to other platforms |
Printer makers run their own libraries too, such as Creality Cloud. Some institutions publish free models as well: NASA, for example, shares models of rockets, spacecraft and planets.
STL, 3MF, STEP: file formats
- STL: the most common format. It only describes the shape, without colors or settings.
- 3MF: a newer format that can hold several parts, colors and print settings. The preferred format on MakerWorld and in modern slicers.
- OBJ: common for colored models or models from tools like Blender.
- STEP: a CAD format you can edit precisely (dimensions, holes). Useful for adapting technical parts.
Whatever the format, the file goes through a slicer first, which cuts it into layers. See our guide to 3D printing software for beginners.
How to pick a good model
- Look at other people’s prints. Photos posted by members (“makes”) prove a model prints well. A model nobody has printed is a gamble.
- Read the description and comments. Designers often explain orientation, supports, the best material or known issues.
- Check the size. The model must fit your printer’s build volume. A compact printer may be limited to about 7 inches (180 mm) per side.
- Avoid steep overhangs and very thin parts at first. Prefer objects with a wide, flat base and few or no supports.
- For resin, look for “pre-supported”. Placing supports on a miniature is a skill of its own, and pre-supported files save a lot of time.
Licenses: what you are allowed to do
A free model is still its designer’s work. Most are published under a Creative Commons license, built from these parts:
| Element | Meaning |
|---|---|
| BY | Credit the designer if you share the model or a remix |
| NC (non-commercial) | No commercial use: you may not sell the file and usually not the prints |
| SA (share alike) | A remix must be shared under the same license |
| ND (no derivatives) | You may print and share the model, but not publish a modified version |
Printing a model for yourself is allowed under almost every license. If you plan to sell prints, check each model’s license, and remember that characters from movies, games and brands remain protected even if a file is freely available. See also what you may sell in our business guide. This is general information, not legal advice.
30 easy prints for beginners
All of these are easy to find on the sites above and print well in PLA on a beginner printer.
To test your printer
- The 3DBenchy, a small boat that became the standard test: overhangs, bridges, fine details
- A calibration cube to check dimensions
- A temperature tower to find the best temperature for your filament
Home and organization
- Adhesive hooks and wall hangers
- Modular drawer organizers (the “Gridfinity” system is hugely popular)
- Cable clips and cable management
- Furniture feet and shims
- Wall mounts for a stick vacuum, hair dryer or remotes
- Plant pots and planters
- A lamp shade printed in “vase mode” (a single wall)
Desk and tech
- Phone or tablet stand
- Headphone stand
- Pen holder and desk organizer
- Case for a Raspberry Pi or small electronics project
- Game controller or console stand
Workshop and repairs
- Replacement knobs and handles
- Clips, latches and broken appliance parts (many already exist as models)
- Tool holders and drill bit organizers
- Drilling jigs
Games, kids and hobbies
- Articulated “flexi” animals that print in one piece
- Fidget toys and moving gear sets
- Board game box inserts
- Dice, dice towers and tokens
- Tabletop miniatures and terrain (ideally on a resin printer for detail: see resin printing for beginners)
- Custom keychains
Decor and gifts
- Lithophanes: a photo that appears when light shines through
- Vases and spiral objects
- Holiday ornaments and Halloween decorations
- Door signs and name plates
- Cookie cutters for play dough or salt dough (for food, read the FAQ below)
Designing your own models
Sooner or later you won’t find the exact part you need. These free tools let you design it:
- Tinkercad (Autodesk): in the browser, by combining simple shapes. Ideal to start, learnable in a few hours.
- Fusion (Autodesk): full CAD software with a free, limited license for personal non-commercial use.
- FreeCAD: free, open-source parametric CAD, with a steeper learning curve.
- Onshape: browser-based CAD with a free plan where documents are public.
- Blender: free and open source, suited to organic shapes, characters and sculpting.
FAQ
What is the best site for free 3D models?
Printables and MakerWorld currently offer the best combination of catalog size, quality and moderation. Thingiverse is still useful for practical parts and older models; Cults and MyMiniFactory for miniatures.
Do MakerWorld models work on other printers?
Yes. Files download as 3MF or STL and open in any slicer. Only the built-in print settings are made for Bambu Lab printers and need adjusting.
What should I print first?
A small test model like the 3DBenchy or a calibration cube, then something useful and simple: a hook, a phone stand or a drawer organizer. They print quickly, without supports, and show whether your settings are right.
Can I 3D print things for the kitchen?
Carefully. Printed parts have tiny grooves where bacteria can hide, and not every filament is suitable for food contact. Stick to items that don’t touch food directly, like holders and organizers.
