I designed this simple car for my doughter using printed in place bearings. I am happy how smoothly it runs( https://youtu.be/tFXGIHvUeTs). As it is also very light it can be easily moved. Its design is manly ment for children just discovering their basic motoric skills (light, moves easily, large round edges), but I am sure that older children will find funny aplications for this toy.
The colors and the design are chosen to match her room decoration.
I recomend to print the chassis with a infill of 10% or less to not waste filament, as it is solid.
The wheels are printed assembled right from the print bed.(just a little bit of turning needed to separate the parts). So the only assembly needed is to snap the wheels onto the car. Note that the round edges on the tires should fit to the fillets of car wheel mount.
A fusion360 and step files are included for remixes.
The model is quite large. If printed smaller the tolerances won't fit. So remix it for other sizes.
