Pencil holder

My project is a pencil/pen organizer. It can hold up to 6 pens, pencils, highlighters, sharpies, etc. and keeps them separate so that they are easy to find. This can help students by providing them with an easy way to organize their different writing utensils. I had some trouble getting the different shapes to move how I wanted them to and go where I wanted them to. If I could redesign this I would probably add more pencil holders. 3D printing would help strengthen my design because I would be able to get a more physical idea of how my design functions and how I could improve it.
