Long before going 3D, I made sketches to determine what my empty containers were about to become. To test the volumes and function, I used paper models, then polyurethane foam models. I followed the same design process I use to create industrial goods. Once all the objects were determined, I used Rhino and Solidworks to make precise 3D models that I turned into .stl files, ready to print. In the next steps, you will find the specifications and the STL file for the selected open source product.
