Creating your own cookware begins with your own 3D printer!!! Printing each componet on it's own and connecting them with wood glue (one pan, one handle, one runner), keeping the runner insert seperate, you can make your own cast iron pan! They need to be placed in the mold in a specific order to ensure that the metal flows correctly. you can create your own pans to cook with at home.
The blender file attached has a version of the Michigan Tech logo inside. Any lofo that is inserted in the center of the pan needs to have draft angle to ensure that the mold turns out correctly.
