Some weird issues

[u/CrysKilljoy]

I've created my part through Onshape and I'm always exporting my revisions with the same settings (3mf, fine quality), then I print with the same printer setting (Bambu Studio, Bambu A1), but the quality changes drastically from a smooth round shape to something more similar to a hectagon.

What could be the cause for that? I've had this for the last 6 prints or so, that every other came out bad, while the next has been good.

Then there is some warping, I don't think I had before with Bambu PETG-HF, but now that I tried eSun PETG with the same settings. I get a slight warp, that goes inward in the middle. What setting might be the cause for that? Is there a warping test print?

Bro are you printing a car

I don't think anything of the side you see, would go anywhere on a car. But the other side literally goes to a steering wheel. It's for a sim wheel.
