All the 3D printed parts aren't required to be waterproof. They are just the structural pieces. Te only waterproof part will be the blue robotics watertight enclosure (the plexiglass cylinder with the two caps made by them.
Little update... I made two TPU flexible "tube holders" for the blue robotics 3inch watertight enclosure. I already printed them and it fits great.

Here is the prop pieces adapted and created for my walker QRX350 motor. The motor and the cables in the rendering aren't exact, I added them just to see it "built" in the computer.

If you look, Blue Robotics went to a 3-bladed prop on the new T200 thrusters, and most professional ROV's also have 3 bladed props. I believe it's the most efficient in water. They are also usually different from boat props, boat props being designed to work best going forward, while ROV thrusters need to push both ways often. Like this with 3 blades cut off... https://www.banggood.com/QX-Motor-30mm- ... rehouse=CN

Just assembled BlueRobotics watertight enclosure and penetrators... Amazing!
Do anyone of you guys know the electrolysis/corrosion effect I could have in ESC wires if not completely sealed? The ESC of course will be sealed. But the copper wires maybe will have some leaks since I will solder them and only put some tape.
Did you had corrosion or electrolysis experiences with your ROV builds?
