Water rocket release

thingiverse

Hey Friends. I've been preparing this project since summer 2014 to share it publicly. My intention was to design a complete water rocket launcher setup. I aimed to test it up to 15 Bar or 220 PSI, which was my ultimate goal. I tested different rockets, ranging from 0.5 liters to 9 liters in size. Please offer your feedback! I'm open to any suggestions and ideas. My components are already tested, and they're working flawlessly, but I'd like to implement some additional features, such as guiding rails for improved performance. This project is a work in progress! Instructions For the Bottle Adapter: You'll need to print it with at least three perimeters using a 0.4mm nozzle setting. For the release body infill, I used a honeycomb pattern with a density of 6%. Take a look at the photo; I utilized a gasket from a beer bottle for this part. Each fin is split into two pieces that need to be glued together. You should always use three of them in combination with "bottleadapter_11mm_fin_1". Secure it all with zip ties on the opposite side. A funnel is really helpful for filling water into the bottles. To achieve a snug fit between the bottle adapter and the bottle, you can try scaling it up or down by 1%. A Teflon strip might also be useful. I printed the entire setup using ABS plastic and sealed it with acetone to get a tight fit.
