TwinJet Speedboat is a lightweight, balloon-powered water toy designed for quick, repeatable launches.
The first two gallery images are visualizations created solely to explain the concept and operating sequence more clearly. All remaining images are authentic photographs of the printed model. The model has been physically tested and works as described and intended.
The inflation adapter is optional. The boat can be used without it, but the adapter makes inflating the balloon and attaching it to the boat much faster. It allows you to prepare several launches in quick succession, keeping the fun going without struggling with the balloon neck or losing air during installation.
Two small rear nozzles distribute the thrust evenly, helping the boat travel straight forward. Their narrow cross-section releases the air gradually, allowing the balloon’s air supply to last longer.
For correct performance, the printed boat should weigh approximately 56 g. Its weight affects the waterline and the position of the rear nozzles, so please check your slicer settings carefully. The included 3MF file already contains tested PETG settings designed to achieve the intended weight and performance.
How to use:
Fit the balloon onto the adapter.
Inflate the balloon through the adapter.
Insert the adapter with the inflated balloon into the boat.
Place the boat on the water and release it.
