The dial itself prints perfectly fine. The holder is a bit flimsy and bends in medium winds on my balcony, but that's not a print profile issue.

No need to adjust anything. They work just fine.

Printed them in 18x18cm in PET on my a1 mini. Stackable snack bowls, great for chips, pretzels etc. They're even doing fine in the dish washer.

also works up to 200% size on my a1 mini. My cats got confused when the toys changed size magically :)
