I had the idea to make a renewable pencil out of an old renewable pencil. So I did that and then added some extra jazz to it. I used an LED to make a pencil that you could write with at night also you could use the pencil led like a torch now, that would actually be very useful. I also did a few other things but you need to read the instructions to find out.

Obtain the Measurements

Firstly I checked online to find the most common pencil on the planet(Faber-castle). After that I ordered a small packet of the pencils. Then I started to measure the pencil the length was 135 millimeters or 13.5 centimeters the diameter of the pencil was 8 millimeters or 0.8 centimeters.
I used the whiteboard feature on zoom to record my findings. I did this on zoom because I brainstormed ideas with my robotics teacher. The idea of the pencil came from me and then I decided to make this as my assignment.
Get the Colors Right

To do this I planned out what colors everything should be. The LED would have the perfect color for its use cool white or soft white. I also figured out the RGB(hex) of the TinkerCAD design.
The paper- f6eee3
The lead - 000104
