Introduction: Christmas Car
While watching a Christmas movie, I got the idea to make my own fanciful push car. This is delightfully noisy when pushed.
My wife made a car using clay. I scanned this with a MakerBot scanner.
Using TinkerCad, I made a hole in the bottom of the scanned car--just the right size to accept the wheel assembly.
Print two sets of wheels and one base. Snap the wheels into the base (red in my model) and snap the base assembly into the car.
Paint the car to suit your taste.
