pencil case

This pencil case is kind of new thing and myself as a student I needed this kind of thing so I decided to create this , in this pencil case I created some buttons that we you want to use you pencil , easer or pen you will only need to pull the button of each thing that you need and it will comes up for you. Creating this pencil case wasn't that much tough but at some point you need to make sure with the sizes. There is only one thing that I would change about this design if I wanted to redesign it , I would change the shape of the pencil case to anther shape. I think for how would 3D printing help strengthen my design I would say with the production of even small designs we will get more efficient.
