The model consists of car body, large wheels, small wheels, large off-road wheels and new small off-road wheels, robust screws as semi-axles, car key serving as a socket wrench and smaller wrench with handle. It is fun for kids to change the wheels. Try it against time ;). Or just choose your wheels, screw them on and place it on the shelf.

Printing is very easy (no supports). Car body is printed on it's side bacause of the threads, screw on it's head (same reason), wheels on the flat side and key on the actual socket wrench. See 3mf files.

Tips:

1.  try color change during car body print to obtain some "speed stripes"
2.  make the top layer on the wheels other than black (white or same color as the body)
3.  make the first layer on screw with other color and the rest with same color as the wheels
4.  scale everything down (I tried 50% and it still works, but it's probably the limit)

Have fun.
