O Marker User 

I noticed that many classrooms at my university had dry erase boards, but no good system for managing dry erase markers, which often ended up dried out or misplaced. To solve this problem, I developed O Marker User - a device for managing dry erase markers, designed to be easily lasercut from one sheet of material and deployed anywhere. The product's take-and-return system helps prevent markers being misplaced or drying out from disuse. This product is now installed in multiple classrooms at Stevens Institute of Technology.

Since making the original version, I have iterated on the design and come up with a Mark II that is more streamlined and has a handy eraser holder.
