Spring Boat - 100% 3D - Wind-Up Mechanism

Turn your bathtub or sink into a naval battlefield!!! Here is the king of indoor battleships, stealthy and fast, it will annihilate any sea serpent or rubber duck, it can accommodate troops of miniatures armed to the teeth. It won't even fear your dirtiest sponge!!! The only limit is your imagination!!!

Hello everyone, I suggest you print this small spring-powered boat, ideal for playing in your bath, it is 100% 3D Printed. No glue, no non-printed parts, even the tools are 3D Printed. Printing and assembly are quite simple, you will find detailed assembly instructions to guide you, as well as a detailed assembly video: 

The powerful spring drives the two propellers which rotate in opposite directions to prevent the boat from going in circles. A pin system allows the spring to be loaded without holding the propellers; by removing it, the boat will start. You have the option of printing two different springs: a soft one and a strong one. You can print everything in PLA. For more power, you can make the spring in ABS, PETG, or PLA CF.

For optimal operation of the spring mechanism, it is necessary to use lubricant on all moving parts.

Print your weapons!!! find a separate print profile with different cannons + 1 new missile launcher.

You also have the option to print a stand to store or display it.

Have fun!!!

Modification 10/17/2025: Increased functional clearances on the propellers to improve mechanism fluidity.
