These markers you can use when changing the summer set of car wheels for winter set and vice versa. At the beginning of the next season they will help you know which wheel is which.
Used symbols readable without knowledge of any language.
Ready for dual color print. No supports needed. Recommended layer height: 0.08 - 0.12mm.
If the markers are too tight or loose, you can simply scale them in the slicer (it will only be a few percent and only in the X and Y axes).
