thingiverse
The ROV/submarine thruster features a permanent magnet coupler and utilizes 12 rare-earth magnets (10x20x2.9mm), a 540-type DC motor, stainless M3 screws and nuts, stainless or brass rod, brass or fiberglass bushes, and silicone O-rings (four 41x1.5 x2, four 44x1.5 x2) for sealing. Additionally, a silicone tube is used to insulate the wires, and it generates a thrust of 2.5N at 12V2.5A; however, results could be improved.
