Cartesian Diver featuring Makerbot's AQUABOT

thingiverse

Print and assemble this Cartesian Diver, named after the renowned French philosopher, mathematician, and scientist Rene Descartes. Demonstrating the mechanics of buoyancy and the ideal gas law, this toy has captivated both young and old for centuries. In addition to printed parts, you'll need a balloon, an empty large soda bottle, and some glue. Tools required include a bowl, sandpaper, and scissors. It makes an entertaining and attractive demonstration piece, perfect as a gift. There's a full video on how to construct Aquabot on YouTube at http://youtu.be/5lzMfchYDaM. The Cartesian Diver strikes at the heart of "Make it Float," exploring the physical property of buoyancy and its significant real-world applications. When I first considered entering this contest, I was intrigued by the underlying physical property that allows denser items to float on water. Research revealed a long history of scientific interest in buoyancy, with numerous scientists contributing to our understanding of this essential component of modern life. Initially, I intended to use coins for neutral buoyancy, but it would have resulted in an unappealingly large diver in a soda bottle container. For that reason, I suggest using the washers I recommend for counter-buoyancy as currency in a mystical realm, where tiny creatures use them for everyday commerce. The contest did suggest using non-US coins! It's been a challenging battle to complete this entry on time... I'm still surprised I managed to finish it with just one day to spare. My enthusiasm for 3D printing goes beyond building functional parts; I aim to develop projects that incorporate design and construction principles, making them attractive and useful. Had the deadline not loomed so closely (I almost forgot to mention how shocked I am that I finished this on time!), I would have made some changes to the basic design. A more ornate pedestal for Aquabot to perch upon and separating the diver at the pedestal would have provided a more striking transition than using different colors. If I had known about it earlier, I would also have liked to swap Aquabot's head with the Antique Diving helmet from http://www.thingiverse.com/thing:128783. Nevertheless, this has been a fun experience, and I hope you enjoy making your own. I've already got several nieces and nephews who are eager to create their own.
