Duplo brick runner assembly

[Rene Rechthaler]

For each wheel color:
71956c0_ ~Duplo Brickrunner Car Axle with ___ Wheels
Wheels in ___ color and axle in color 494.

76139 Duplo Brickrunner Car Base with Wheels (Is this needed at all?)
All subparts in color 16?
Is a 71956 with default colors needed?

because the axle is always metal, you could hardcode the axle and leave the wheels in col16. (no need for each color)
then make one fully col16 car base assembly and one for each wheel color. (base always col16)
