Inspired by the design of other contributors to Thingiverse and the Make It Float Challenge that was issued, Mike Blakemore decided to design and print his own, fully functional, miniature, 3D printed submarine. Named The Catfish, it operates using an air pump rather than compressed air and is capable of carrying a diminutive cargo underwater. The colorful creation has been made available to others through Thingiverse and I wouldn't be surprised if an army of tiny submersibles are spotted across the nation as a result.
