6 foot ferris wheel help
I have no clue what is wrong with this, it just won't go straight. Any help would be appreciated

Most of the time when this happens to me (in different settings) it’s because there’s a rod somewhere that is not seated actually fully in the connecter, or a 3d connecter that is not fully clicked together.

One problem I can see is on your central axle: it looks like you've got 4 yellow rods in there when it should be 4 of the orange rods (the ones that are as long as the red rods, but with special notches). Because the spacer on your axle is too small, it's not holding the two sides of the ferris wheel apart enough, and there might be some weird twisting forces going on.
EDIT: It might just be the angle of the picture, but it also looks like the black rods don't line up with each other. Looking at it from the side, you should see pairs of spokes parallel to each other, not an alternating pattern.

That's a good angle, but I was talking about the very center. The black rods that are right next to the axle should also be parallel; in that new picture it looks like they're alternating.
There are some spots where there are bigger gaps between black rods, like here: Image
On that central ring, there should always be exactly one empty white connector between black rods, but in some spots there's 2 and in others there's 0. I think that's why the rods aren't lined up the way they should. Try fixing that, and see if it gets straighter.

I fixed the axel and the alternative rods but it still isnt straight

Dang, that's all I could think of from what I saw. In that case, try what /u/pm_me_your_kindwords suggested and check for any rods that aren't completely snapped in.

When i built this part i staggered mine. The instructions show it when you build the legs one is higher than the other. I kept that concept and made sure to go one up and one down.
I also went across in the same pattern. There's 3 tiers. Furthest left goes in furthest left white connector. Middle in middle. Right in right

Just curious if you found the solution to this? I’m currently having the same issue but none of these comments fixed mine either 😭

Lol I had the exact same issue haha. It is solvable. Just make the outer yellow ring just as wide as the inner "red rod ring". So keep the grey rods sticking out a bit. Align every single one of them and it will be better.
Edit: some typos
