I like motorcycle racing and I work with 7-axis CNC DED machines for a living. combining these two things allow me to make accurate models of the racetracks I've ridden. I like to share these files as I think a 3d printed racetrack I've ridden (including laptimes 3d printed on a seperate 'plaque') on a wall look pretty dope. you can even frame them if needed. I will be designing track logos to print with the track files as well in the near future
