You will land on a tinkercad design that you will be able to customize. For example you may change the color. You may modify the size. or add extra details, for example some text. Click on export and choose either .obj or .stl format. The key must be designed in such a way as to allow a 360° rotation inside the 3D design. Kids can produce the key either on tinkercad (it will need to be 3D printed afterwards) or via a 3D pen. To figure out the correct size of the key, they will need to observe the size of the 3D design. To do so on tinkercad, select the measuring tool, and place it anywhere on the  plan. After that, just left click on the object whose size you would like to measure.
