For this project, we created a pencil holder which fits into the open holes in the tables. We had to measure the size of the holes and create a pencil container in SketchUp which fit into each hole. We also added six holes on the side to hold extra pencils and another larger hole on the other side to hold smaller objects such as paper clips and erasers. The center hole which is meant to fit into the tables and is about 5 1/2 inches deep. In the end, we also made a small cover which can slide over the top of the container to close it off when it is not in use.
