thingiverse

Insert an unfolded paper clip into the hole located at the bottom rear of the boat, then bend it towards the front side closest to the vessel and secure a rubber band around it. Loop the other end of the rubber band over the nub situated near the front of the propeller. Next, thread the propeller through the paper clip and seal the connection by closing off the loop. To activate the device, simply spin and release it to initiate motion.
