My first "Designed for 3D Printing" Project from last year. Nothing special but reliable and I think it looks good. Initially I planned to inlay the windshields but decided to fuse it in to the body (left enough of a separation that it can be easily painted if desired).
The wheel clips will probably fit a bit too loosely to be used with young children (can be pulled off).. if nothing else you might try gluing them in or let me know and I can provide a tighter fitment.
