|Step_Title=<translate><!--T:14--> Have the kids produce a key</translate>
|Step_Content=<translate><!--T:15-->
The key must be designed in such a way as to allow a 360° rotation inside the 3D design.

<!--T:16-->
Kids can produce the key either on tinkercad (it will need to be 3D printed afterwards) or via a 3D pen.

<!--T:17-->
To figure out the correct size of the key, they will need to observe the size of the 3D design.

<!--T:18-->
To do so on tinkercad, select the measuring tool, and place it anywhere on the  plan.

<!--T:19-->
After that, just left click on the object whose size you would like to measure.</translate>
