Torpedo Pool Toy

Let's 3D print some pool toys! There's this toy torpedo that many remember playing with as a kid in the pool - you throw it underwater and it rockets across the pool. The toy works because it's neutrally buoyant, which means it has close to or the same density as the surrounding water, so it neither floats nor sinks, and instead moves easily through the water. Now you can print and assemble your own! To see the design process and what it takes to put one together, read our article How To: 3D Print Your Own Torpedo Pool Toy.
