The design is a growing pencil, which solves the problem of pencil head waste and makes full use of the pencil. The pencil tail is designed as a screw connection structure, so that the pencil can be connected with other pencils after being used to the tail position, thus achieving the purpose of not being wasted. The whole pencil is made of logs, the shape is mild and smooth, and the tail is similar to the shape of flowers, giving people an interesting feeling. This product is a small design I made in my sophomore year. If I think about it again, I still want to send out the original process. Although the sketch is a bit ugly and the modeling and rendering are also very good, now I look back and have a different feeling. The four years of college passed quickly, and there was a place where the record grew well. I remember that I accidentally saw another similar design in a competition after finishing my homework, there will still be different solutions to the same problem, but when I designed it, I really didn't see it. I still want to send it out and record it.
