Sharpwriter Pencil for Custom Colors

After Adam Savage complained about the new version of Sharpwriter plastic pencils not giving him the right vibe, I decided to model the pencil body so I could 3D print it in colors that matched MY vibe.

The barrel has a pair of straight internal channels that keep the lead holder from twisting. When the lead holder engages with the tip assembly spring and the tip/spring is rotated it causes the lead holder to move axially - extending or retracting the lead.

This project requires a donor pencil from which you will harvest the internals - lead/lead holder, tip/spring. and eraser.

1. Remove the eraser
2. Turn the tip/spring to retract the lead until it is visible from the top
3. Remove the led/leader holder by pulling it straight out of the top
4. Remove the tip/spring with a pair of pliers
5. Drop the lead holder/lead down the 3D printed barrel so the lead extends from the bottom
6. Start installation of the tip/spring by sliding the lead into the center of the spring
7.
