As a subscriber, I'm surprised you haven't noticed this "little thing"... The fin area affects dramatically the centre of pressure of any rocket. CP should be always placed behind/below the centre of gravity (CG). As a rule of thumbs, at least at a distance that matches the diameter of the rocket. How can you be sure that this "one scaled size" fits all, works? I mean, in terms of having a predictable flight trajectory. Keeping the same diameter, if you build a 50cm water rocket, or a 2 meters one, will require a different fin area.

That's a very neat, scaleable design! Well done! :) I think this is especially nice for beginners to water rocketry and 3D-printing. We made a similar design a while ago, but it's not scaleable because it connects through the nozzle to the rocket. Looking forward to put the two stage water rocket footage into our water rocketry in 2018 video. ;) Greetings from the team Julian

Thanks, Julian! If there's time, perhaps we will publish some more video of the stager. This is a busy time of the year! The hollow design is something we've used for a long time. The simple way of scaling is the "fell off the toilet while hanging a clock and hit my head" moment when the scaling idea was born.

The fin area can be increased or decreased by scaling the fin can in the Z axis when printed, but in reality most people who build water rockets generally make whatever size fins look nice to the eye, and then use clay or something packed in the nosecone to move the CG to where they want it. Thanks for the question. Your feedback is appreciated! Cheers!

My Cub Scout Pack just got into water bottle rocketry and we have been tinkering with simple cardboard fins attached with tape or hot glue. I’d love to show them how extensive the hobby is and that the sky is the limit when it comes to design and materials. However, I don’t have access to a printer. Do you by any chance offer pre printed fin sets and nose cones for a regular two liter ( coke or Pepsi ) type bottle? Any help or advice you can offer would be greatly appreciated!!

We had them years ago as well, but the ones they sold go only 50-100 feet high, so we started making them from soda bottles and putting many bottles together you can make them go hundreds of feet high. If you make them with exotic materialsd like carbon fiber, then can go thousands of feet high. The best part is that they are very good at lifting payloads, so they make great platforms for cameras or other heavy experiments.

Try 89mm and only print a little but of the fins to test fit. You can then decrease the scale until you get the exact fit you want. Every printer is a bit different, so it's hard to know what scale to use until you do the test fit.
