This is an adaptation of another model made by Redditor user u/daandruff for reddit user u/speakthat's child whose favorite pillow features a yellow car very similar to the model made of it. You can find the thread here Help turn my baby's favorite toy car print into a 3D model and an image of the car on the pillow below

The author remixed this model.
I've just warped the dimensions a bit in an effort to try to give it more of a cartoony look.
