We have a Playtive wooden street set from Lidl. But we always don't have enough parts, so I just printed them out.

Of course, you can also just use the printed parts instead of the wooden ones.

UseR3D PLA Filament in Matte Ash GrayAfter printing, the appearance is perfect, but it's easy to get scratched.

The street markings are imprinted in the model and are only 0.01mm in height, so the slicing software won't make much difference there, but the "Smart Fill" drawing function will detect these markings. Or you can use the 3MF files I've pre-colored for Bambu Studio.
