I created my own mold of a submarine, the goal was to create a remote control submarine to use in a pool. The materials that I used were a computer app called 123D Design and a 3D makerbot printer. I only used two tools a computer and a 3D printer. The hardest part was realizing that I will only be able to a create fro no because the goal was to create a working submarine. Although, the most fun part was creating and actually seeing my idea come out just the way I wanted it to. I learned how hard this project was and how long a process takes. If there was one change I would make I would make it large enough to fit my GoPro inside the submarine.
