The world’s first 3D printedradio controlled boat powered by the rainbow! It uses H2O + sunlight in order to power the jet propulsion system. It’s gone before you can get the camera up. In reality I 3D printed the frame using a bunch of colors, hence the rainbow scheme. It’s powered by a water jet system, meaning the propeller is protected by the frame. This means you can drive the boat in really shallow waters. The acceleration was unexpected, but it was quite slow due to the heavy plastic. The motor also got hot after only running for a couple of minutes.
