Learn how to design the Japanese framing joint known as Kabuto Ari. While this joint was primarily used in building frames, it appears as though it can be used in furniture as well.

I demonstrate how to model the joint in FreeCAD, while trying to avoid the Topological Naming Problem. Also I'll show you how to assemble the joint using the A2Plus workbench, and animate the assembly using the Exploded Assembly workbench.
