This is my submission for my class's rocket project. I made this on Tinkercad using Codeblocks.

Step 1: Step 1: the Fins

I'm no rocket scientist so I don't know what these things are called so I'll call them fins. You should see a picture above of how to make the 4 fins. Start off with a wedge and change its color to black, unless you want a weird colored rocket you should remember to change the colors of your objects/shapes. After making the wedge, we will need to make it smaller so we are going to make 2 invisible squares to cut up parts of the wedge. Afterwards we just put them in the correct locations and rotations.

Step 2: Step 2: the Hull?

Again I don't know what its called so I named it "Thing in the middle" but I think its called the hull so I'll be referring to it as that. The Hull is the biggest part of the ship but inversely the simplest part of our Codeblock. Its just 2 cylinders, but you should make sure you change the proportions/size of the cylinders. After that its the simple process of moving them up to fit with the fins. (also you might of noticed the shapes are floating but don't worry that's intentional and is for the last part which needs to go under the rest of the rocket)

Step 3: Step 3: Upper Fins

Its time for Fins 2 Electric Boogaloo. These are probably the smallest piece of the rocket but the code is not short at all. What this code is basically doing is making a wedge then cutting it down using invisible squares then moving the wedge to the correct position. Afterwards we copy that wedge then rotate and move the copy to make the second fin.

Step 4: Step 4: the Head

Its just a cone which I made a bit bigger and moved to the top of the rocket. That's it...on to the last step!

Step 5: Step 5: Flames!

To make the flames we just took a roof shape, scale it to be higher then make smaller and recolored versions of it. Afterwards we move them to the bottom of the rocket, that's why the rocket parts have been floating all this time. If you think the "flames" don't look that good then you can move the rocket up even more to show more parts of the flame, if that's not enough you can also try to make your own flame with a more realistic shape. But trust me I have tried making better flames and it either takes too long or doesn't look like a flame.
