 * BOLTSFC (github link) is an extension that allows you to use the BOLTS "Open Library for Technical Specifications", which is a collection of objects like nuts, screws, bolts, and so on, parametrically defined.
 * CadQuery allows users to design parametric 3D CAD models defined by the CadQuery CAD scripting API. It includes a full-featured editor with features such as auto-completion, syntax highlighting and checking, line numbering, and code folding. Example scripts are included to make the user get started with using the API. Script variables can be edited dynamically through the use of a parameter dialog. This workbench also includes cqparts, which is a library that adds support for parts and assemblies with constraints on top of CadQuery.
 * Curves is a collection of tools to create and edit NURBS curves and surfaces.
 * Defeaturing provides tools to edit STEP objects to remove features like holes, faces, and edges, and perform some operations with the simplified objects.
 * Fasteners Workbench is a workbench that provides various fasteners, screws, bolts, nuts, etc., to attach to your model. Development happens at Fasteners Github repo (github link)
 * FCGear (github link) is an extension that adds many different gears like cylindric involute, involute rack, cylindric cycloid, spherical involute bevel-gear, and crown gear.
 * frame (github link) is an extension with tools to create frames and beams, including two intersecting beams, in which one beam is cut by a plane or by another beam.
 * Lithophane (github link) is an extension to convert a provided image to a "lithophane" for 3D printing. A lithophane is an image that can only be seen properly when illuminated from behind.
 * nurbs is a collection of scripts for managing freeform surfaces and curves.
 * parts_library (github link) is an extension that downloads a library of parts in Step format or in FreeCAD format  that can be imported into a FreeCAD document. Users can contribute content to this library by forking the repository, adding their own parts under a permissive CC-BY 3.0 license, and submitting a pull request to merge the new objects.
 * pcb (github link) is a workbench that allows the user to import and create printed circuit boards (PCB) in FreeCAD. It supports layers, colors, transparencies, importing Step and Iges models, and displaying holes and vias.
 * reconstruction (github link) provides utilities to reconstruct models from images.
 * retr3D (github link) is a framework designed to model and manufacture 3D printable parts starting from electronic waste, in order to build more 3D printers. The intention of this project is to recycle e-waste, promote 3D printing, especially in developing economies, and in this way reduce the amount of waste that goes to landfills. Using locally built, and inexpensive 3D printers could also be a way of localizing manufacturing, thus stimulating the local economy of these regions.
 * Silk is a collection of NURBS surface modeling tools focused on low degree and seam continuity. Silk is the new name of the NURBSlib-EVM project.
 * SlopedPlanesMacro (github link) allows you to build figures controlling the slopes of the faces of objects.
 * symbols_library (github link) is an extension that downloads a library of SVG symbols that can be used in FreeCAD, particularly in the TechDraw Workbench to produce technical documentation. Users can contribute content to this library by forking the repository, adding their own symbols under a permissive CC-BY 3.0 license, and submitting a pull request to merge the new objects.
 * ThreadProfile (github link) allows to easily create parametric 2d thread profile object compatible in Part and Part Design workbenches.
 * timber (github link) is a workbench to produce wood and timber objects.
