The STEMFIE WB project started a while ago, after a long hiatus now has come back to life with better icons and new STEMFIE components: plates and shaft.
The main advantage is that the created parts are parametric and are easy to update. Also being on FreeCAD gives you access to all tools and features of it and other external WB, as Assembly. You can find it on the FreeCAD Addon Manager. Feel free to open issues or pull requests.
More STEMFIE components will be added soon(TM).
