Traktor Trailer Bburago

My son got this Bburago Traktor and it came without a trailer.

So I remixed the Gaslands Shipping Container with Sliding Lid and the TP Car-Wheels.

I altered the wheels so that a M4 rod fits and the container got the complete lower and the attachement for the traktor.

As an axle I used a M4 threaded rod and printed some M4 nuts.
