The paddle wheels
I liked Simon’s idea of a paddle wheel to power to boat. It reminded me of the river boats navigating the Mississippi river in the old days. Since the model is 37cm long already, I chose to use two paddle wheels instead on one and locate them on both sides of the vessel instead of at the back. I made the two wheels on the 3D printer as well as the bracket and support for the miniature gearmotor. I used two gears from my collection of discarded parts to connect the motor to the driving shaft. The paddle wheels came to life in the attached video.
