Introduction
In this activity, kids will have to design and subsequently produce a key that is capable of accomplishing a 360° rotation inside a 3D printed keyhole.
Watch this video to find out how it works.
Matériaux
Outils
- 3D printer, or 3D pens
- computer with internet connection
- measuring tools
- paper and pencils to sketch drawings
Étape 1 - Set up an account on Tinkercad
Once you're done, enter this address on your web browser. You will land on a tinkercad design that you will be able to customize.
Étape 2 - Personalize the key crack design
For example you may change the color.
You may modify the size.
or add extra details, for example some text.
Étape 3 - 3D print the design
Click on export
and choose either .obj or .stl format.
Étape 4 - Have the kids produce a key
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.
