Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4405896.
Made just to make a point on reddit: https://www.reddit.com/r/3Dprinting/comments/gsfs6v/i_will_3d_model_any_race_track_for_you/
Downloaded the SVG file from Wikipedia, cleaned the file up using Inkscape and finalized the 3D model on Fusion 360. Took me less than 10 minutes. Pitlane not included, just like the reference on the link above.
