Pencil Vending Machine

This project was an idea suggested to me and my students for a fundraiser. Students learn to print the main object(s), then complete the circuitry needed to make it a functional model. As for the shell that goes around this, we simply used posterboard because it was a little quicker to make than 3D printing all of the walls as well. Teachers throughout the school loved this idea.

This project was not solely my idea, just the 3D model. You can find the full video with instructions on how to build it here:
