Where to Find 3D Models to Print: Printables, MakerWorld and More

You do not need to design anything to start 3D printing. A very large number of ready-made models are free to download. This guide lists where to find them, what each site is known for, how licences work, and what to check before you press print. It is research-based, drawn from the platforms' own documentation and help pages, not from our own download tests. Site features change, so check each site for its current rules.

The short list

• Printables: run by Prusa; models, 3MF projects and ready-sliced G-code files; built into PrusaSlicer.
• MakerWorld: Bambu Lab's platform; models with attached print profiles and photos.
• Thingiverse: one of the oldest model sites, founded in 2008; huge archive and many remixes.
• MyMiniFactory, Cults and others: platforms that Prusa lists, some with both free and paid models.
• Your own models: Tinkercad and other free tools are easier than most beginners expect.

What file types to look for

Prusa's documentation says models should be in .stl, .obj or .3mf format to be used in its slicer. STL is the plain shape of the object. 3MF can carry the shape plus colors, settings and plate layout. Our guide to STL vs 3MF vs G-code explains the differences. A model file must be run through a slicer to become printer instructions; see what is a slicer.

Printables

Printables.com is Prusa's own platform. According to Prusa's knowledge base, you can download both object files and pre-made G-code files for thousands of projects, and the site is built around its community, including a Groups feature for finding people in your area.

Since PrusaSlicer 2.9.0, Printables is built into the slicer. A Printables tab sits near the Printers tab. Prusa says you can search the database without leaving the slicer, download models or 3MF projects straight into PrusaSlicer, and send G-code directly to a printer registered in Prusa Connect, when the G-code was sliced for that printer.

Good for: any printer brand, since models are plain STL or 3MF; users of PrusaSlicer.

MakerWorld

MakerWorld is Bambu Lab's model platform, documented in the Bambu Lab Wiki. Its distinctive feature is print profiles. The wiki says that when someone uploads a print profile, MakerWorld requires at least one photo of a model printed with that profile to demonstrate printability, and that high-quality profiles offer real improvements such as wider printer compatibility, multi-color versions or tuned slicing parameters for reliability.

The wiki also describes Featured and Exclusive model programs and creator commission incentive rules, so the site has a creator-reward system on top of free sharing. Its Featured model guidelines say models are evaluated on content compliance, design quality, printability and user feedback.

Good for: Bambu Lab owners who want a model that opens with settings already chosen. If you own one of those printers, our Bambu Studio guide shows how the slicer side works.

Thingiverse

Thingiverse is a long-running design-sharing site. Wikipedia lists it as launched in 2008 by Zach Smith as a companion to MakerBot, and says it provides mostly free designs under GNU General Public License or Creative Commons licences, with contributors choosing the licence type. It is widely used for repair parts, decorations and organizers, and encourages derivatives and remixes. Wikipedia also reports that MyMiniFactory announced the acquisition of Thingiverse from UltiMaker in February 2026.

Good for: older, well-known designs and remix chains.

MyMiniFactory, Cults and other marketplaces

Prusa's guide lists Thingiverse, Pinshape, YouMagine, Yeggi, MyMiniFactory and Cults as other platforms worth trying, and notes some have both free and paid models. Wikipedia describes MyMiniFactory as a London-headquartered platform founded in 2013 that opened an STL store in 2018 where designers can sell files.

Paid models can be worth it when you want a specific designer's work and want to support them, as Prusa's guide puts it. For everyday functional prints, free models are usually enough.

Using more than one site

Prusa's list includes Yeggi among the platforms it has found helpful. Whichever site you use, check each model's licence on the page where it is hosted.

Licences: what you can do with a download

Prusa notes that models are generally free to download under Creative Commons Attribution Non-Commercial licences, which means they should not be used commercially and you must always credit the author. That is the common pattern, but each model carries its own licence, so read it.

Creative Commons describes six licence types. In short:

If you plan to sell prints or share modified versions, check the exact licence text on the model page. This is general information, not legal advice. Paid models usually have their own licence terms.

How to pick a good model

1. Look for photos of real prints. A render proves nothing about printability. MakerWorld requires a printed photo for each profile for this reason.
2. Check the print orientation and supports. Prusa's design guidance notes that printers cannot print in mid-air and that surfaces above supports will not have the same finish as side walls or top fill.
3. Read the description for recommended settings, such as layer height, infill and material.
4. Prefer models with remixes and comments from people who report results.
5. Match the size to your printer. See our guide to build volume.

Prepare the file before printing

Open the model in your slicer, check its size and orientation, and slice it. If a model looks broken in the preview, such as holes or missing faces, try another download or a remix before spending hours on it. If you are brand new, our walkthrough on how to 3D print covers the full path from file to finished part.

Start with a test print

Bambu's wiki lists community models that are ready to print, including the 3D Benchy boat, a bed scraper and a foldable phone stand. A small, well-known model is a good first print because many people have printed it, so comparing results is easy. For more ideas, see what you can make with a 3D printer.

Making your own

When nothing you find fits, design it. Prusa's guide recommends Tinkercad as the easiest way to create models quickly, an online editor that needs no installation, and Autodesk Fusion as a more capable but more complex option. It also lists OpenSCAD and Blender as free options. Our walkthrough of a first Tinkercad design is a good place to begin, and the overview of free CAD software covers the rest.
