This is a bumper car model based on the 1959 Lusse Auto Skooter. The car is modeled full-scale and can be scaled to your desired size. My samples are printed in HO scale on a Mars 2 Pro, scaled to 1.149% (the slicer shrinks the model when imported so I have to enter 1149%). The cars are printed with the nose tilted up. The steering wheel is printed vertically and glued to the car after paint.

The stinger can be made from a piece of brass rod and glued to the mount on the rear of the car.
