My project is designing, printing and testing a functional 3D submarine. I chose this project because I like to use my 3D printer and making custom toys. I was not able to test if the pumps work because the pump design was not viable. The submarine did float and was watertight. I think this is important because I want to make a submarine toy that is cheaper and better than buying one.

I love how you showed your consistency over the years on carrying out this project. You have put in the work and you have shown great dedication. You should be very proud of yourself! In addition, I also love your prototype, how you showed your motivation for the project, and the entire concept of your work.
Your Neptune submarine project shines with thorough research on peristaltic pumps and motors, meticulous iterative designs using digital modeling and prototypes for ballasts and threads, dedicated execution in 3D printing and balancing calculations, creative water-driven steering innovations, and professional presentation with equations and references, keep engineering, young engineer!
