After asking a few teachers what is something they wish they had to make their day easier, we designed and printed a cup holder to help teachers keep their hands more free for our classroom project. Teachers need a cool gadget to hold their necessities on their messy desks as well as when they are walking around campus. This cuff attaches to a water bottle and holds their phone. It is elevated on the cup so they could even charge their phone while it is on cup.
We made a few versions of the holder to fit the cup perfectly before we added the attachment for the phone. Once we had the size correct, we measured an iPhone and added that part.
