Couldnt find any current 18" F1 coaster to my liking, so i created my own from scratch.

Best print orientation is face down on the buildplate, like in my orcaslicer 3mf projectfile.
This way, the printed colors gets nicely squished together without a specific need to iron.

This also opens the option for a small rim on the bottom, to lessen any interface to the table and less wobble.
On a PEI textured sheet, the texture makes it pop even more.
 

Orcaslicer 3mf projectfile is AMS compatible and prepositioned and colored, and printprofile included (0.16mm layerheight makes 2 layers of ‘printed color’
(Orcaslicer 3mf project files arent compatible with bambustudio projectfile for some reason)

If you load the single tires, you can scale them to wish (on the pictures the X and Y are scaled to 10cm, Z remans 3.5mm)

If you cant load the projectfile id suggest using the .step files as they show the part names to color
