All of the #freecad parts in the post last night are from a 1970's drafting textbook that I have. I decided to try modeling the entire assembly to show that you can do it just fine using the Assembly3 workbench to put it all together after modeling each individual part. It really wasn't any harder than doing it in something like SolidWorks. @FreeCAD is an incredibly powerful tool, and it makes me happy to see more and more people realizing that and using it.
