Carrera Hybrid Complete 1:8 Track Tile Set

Just for the looks: I recommend a color change on the last 2 layers.
Of course you can also print the parts in one color.

PETG, 0.4mm nozzle, 0.28mm DRAFT mode works perfectly.
The connectors are a snug (0.1mm) fit.

I did not design a narrow section and finish line, because they are basically just straight parts.
