[Peter]’s dive scooter is almost entirely 3D printed. That includes the ducted fans/thrusters. The electronics are what you would expect from a grab bag from Hobby King and include two 2530 sized 400Kv motors from Avroto. These are massive motors made for massive quadcopters but they do seem to work just as well pulling a human underwater.
While this dive scooter was a marginal success, there were a few problems [Peter] had to work through. These were the lowest pitch propellers [Peter] has ever printed. To be fair, most of the props [Peter] has printed were used in air, not a fluid that’s hundreds of times denser. The electronics held up very well, considering the bath in salt water.
