UPDATE: I added extra optional designs to fit some tastes and just because the other design was very basic.

• Added the design "Hard to print" main body with Aerodynamic Fins
• Added a steeper Nosecone (comes down to preference)
• Added an additional middle extension piece to just glue in

So I built a little model rocket myself out of a PVC tube and was wondering if It would be able to print and fly well too. I have yet to start it since the engines I ordered haven't arrived. I will update this after I tried it.

EDIT: I tried it, it flew flawlessly, way higher than my main rocket (still not a professional cardboard tube one) just because its lighter, the only problem is its stuck in a very high tree and I haven't gotten it out yet to look at possible warping or internal damage

2nd EDIT: I got it back, no damage whatsoever!

Feel free to leave some comments.
Thanks in advance for trying my model!

DISCLAIMER: If you print this rocket with the extension, its weight is gonna come close to the Limit of a D9 Motor, which is the biggest commercially available motor in Germany. I know my model is way oversize of an actual model rocket and weighs pretty much double of what a professional rocket should weigh. Keep that in mind while using my design. It is not gonna fly as good as a cardboard tube design just because it is 3D printed.
