This is a modular rocket display stand.

Allows you to store/display your rockets vertically rather than horizontally.

There are three versions of the middle sections. One has arms for 18mm engine mounts. The Second has arms for 24mm engine mounts. The third is just a spacer to add space/height to the tree without adding more rockets. Each middle section rotates freely to allow you to orient each section of rockets so they do not collide.

Finally, there is one top section that has 18mm arms and will complete the tree.

Print as many middle sections as you need to store all of your rockets.

I recommend either printing the base with a high infill to add weight to the bottom or add weight to the base after printing (I used lead shot) to ensure the entire tree is stable if you will be adding a lot of sections.

Also recommend 24mm engine rockets on the bottom, with 18mm on the top to keep larger rockets, and weight closer to the stand. DO NOT PRINT WITH SUPPORTS! You risk leaving a little support material in the pin cavity which will create some space between sections. This will result in the tree starting to lean as you add height, which will not end well.

Printing dimensions are optimized to the bed size of a Bambu X1 printer. I had to remove the pin from the base and print it separately to keep it within the Z height of the printer.

I made a second version of this that uses a 1" wood dowel the entire length which provides significantly more rigidity if you are finding your printer prints these parts too loose.
