Functioning Torpedo for RC Boat

Been working on a PT Boat. Decided I’d want to make working torpedo’s for extra fun.

All parts printed on my Noir with Siraya fast. Used a micro lithium ion batter, a small reed switch, small brass tubes for shaft and tub, and the motor is from a 9g servo.

Printed the entire boat, totally inefficient and heavy, but I intend to make a plug and mold of it so it’s more for parts fitting, and it moves around the water still.

Here is a bathtub test.
