Toy Truck for infants under 8

This is a toy truck that I designed for my son in OpenSCAD.
Front end of this toy truck looks a bit like a face.
The cargo container is hinged in the back and can be tilted.

Simple to print, without using any supports.
Can be printed in any material you like and of course also in any color.
Preferably, printing in different colors is better than paint the parts.
Model is designed with mishandling in mind and should be able to withstand some abuse by children but no liability is assumed.
