This repository contains a library of Parts to be used in FreeCAD. It is maintained by the community of users of FreeCAD and is not part of the FreeCAD project, although it is made with the aim to be used as a repository of parts by FreeCAD in the future.

Contributing to the library

If you made some interesting objects with FreeCAD, why not share them here? Others might find them useful. The procedure is simple:

  1. Create a github account for yourself
  2. Fork this repository using the "Fork" button on the top right corner of this page
  3. Follow the github instructions to clone your fork on your computer
  4. Make all the changes you need, create more folders if necessary, and place your files in them
  5. Upload (push) your changes to your fork on github (refer to the github help for instructions)
  6. When your fork has been updated, you can submit a pull request to have your changes merged into the official library. A member of the community will review your proposed additions and accept the merge.

Each Part should be correctly named, and placed into subdirectories by family or type. They should also be available in both .FcStd and .stp formats, and optionally in .stl format (because github lets you visualize them). They should also be as simple as possible, and parametric so users can easily change their dimensions. In the file properties of each .FcStd file, the author should also be mentioned, and the license information if available.

Note: Please DO NOT use accented characters in your file names, thanks!!!

If you are interested in contributing to this library on a more long-term basis, please ask for write access to this repository on this FreeCAD forum thread:


All Parts in this repository are licensed under CC-BY 3.0 Each Part is copyrighted by and should be attributed to its respective author(s). See commit details to find the authors of each Part.

If you are uploading parts to this repository, please make sure you are the author of the model, or otherwise that you have right to share it here under the CC-BY 3.0 license, and make sure the author is mentioned in the commit message.


As the library is part of the FreeCAD addons, the easiest way to install and keep the library updated is through the addons installer, where you will find it there under the name 'parts_library'.

Warning: the library is huge in size (+/- 1 Gb) and therefore might take a very long time to download

We are trying to find ways to workaround this. If the Addons Manager takes too long to download, you can also download and install it manually by following these steps:

  • In FreeCAD, find which is your user modules folder by entering or pasting App.getUserAppDataDir()+"Mod" and your usr macros folder by entering App.getUserMacroDir() in the Python console (found under menu View->Panels)
  • Download the library as a zip file using the green "clone or download" button in the top right corner of this page
  • Unzip the zip file you just downloaded. You will get a "FreeCAD-library" folder
  • Rename that folder from "FreeCAD-library" to "parts_library"
  • Move that renamed folder to the modules folder location that we got above
  • Inside the FreeCAD-library folder, you will find a PartsLibrary.FCMacro file. Copy that file to the macros folder that we got above
  • Restart FreeCAD. The parts library will be installed, and the addons manager will recognize it as installed. You can launch and use the library by executing the PartsLibrary macro from menu Macro -> Macros...

The library is a simple container for FreeCAD (.fcstd) and STEP (.stp) files. You can download it anywhere and import its files in your FreeCAD projects. Inside the library, there is a FreeCAD macro (PartsLibrary.FCMacro) that you can place in your FreeCAD macros folder. That macro creates a browser window inside FreeCAD, from which you can easily add the parts by double-clicking them.

Sharing your models from the macro

The macro also allows a couple of other possibilities, such as adding new objects, and sharing your objects with others. To share, you will need the python-git package installed on your computer, and an online git repository you have permission to write to. The easiest way to obtain that is using the "fork" button on top of this github page.

Once you have made your fork, you will get an URL from it, that you can use in the macro's config dialog. After that, once you have saved your models to the library, you can push them to your online git repository, and, if you wish, make a pull request on this page to see your models integrated to the official library.

You can’t perform that action at this time.
