Strange Line Patterns

Printing with 5 wall lines, I get these rectangular artifacts on the lower rim layers. (1st picture)
On the smaller top layers all lines run the full circle. (2nd picture)

Any Idea how I can avoid this?

Could you please post a Factory File for this? The settings are helpful but their interaction with the model file is important for things like this.

Here's the .factory and the .stl.

Some issues in STL file. Gaps probably. If you use advanced tab and you change parameters in Thin Wall Behavior everything change is better. But also not perfect.

Yeah, they are separated bodies in the STL:

A proper printable STL file should have only one body (expect doing some multimaterial/multicolor print)

It should be composite part in STL file. Try to change it from CAD software. It should help. Or you can use some STL repair www site.

Here you go......a repaired and slicable part!

I would recommend saving all the separate parts and loading into your own installation. Just in case saving a factory file from one environment & loading into another causes issues.

For the record, I did the following:
Used the Separate Connected Surfaces function
Increased the size of each of the spokes by 1%
Ran the rim through 3D Builder to repair it.

Took 10 mins to diagnose & sort out! Think I've earned a coffee!

Thanks a lot guys! When in Hamburg, feel free to get in contact for a coffee. :)

Beeing a newbie in Fusion 360, I had done it as component with multiple bodys.
Following your advice, I joined the bodies before STL export now, leading to a reasonable slice:

Thx again!
