Yin Yang Espresso Cups
These are cups that I designed and based on the Yin and Yang symbols. A pair of these will cleanly mate together and form a circle.
I designed these in Autodesk Fusion 360 and then milled them out of 6061 aluminum using a Haas VF 2SS mill. The app was also used to generate the toolpaths.
