Simply Front Loader. The model can be disassembled into individual parts at any time with the help of the attached screws, it is possible to replace the wheels with alternative wheels.
The model should practice children's motor skills, control of tools (screwdriver and screws) and at the same time involve them in playing with the model.
This is the next model in the series, where several more models in a similar spirit are planned to be used. Watch my new models and have fun :)

Recommendation:
after printing the individual parts, check whether there are no sharp edges on the model, residues after printing, remove these with an edge-knife, file, or sandpaper.
Use a screw: if the screw is to be screwed into the model, I recommend using a little strong dry soap or soapy dry crack on the screw - excessive force can destroy the model, dry soap can help.

I recommend first inserting and screwing the sample into the hole intended for it. provided that it is stiff, it is possible to help with a little dry soap. When first screwing in, ideally two screws in, one screw out to the end of the hole, then unscrew and screw in as it should be (including parts). If it was a moving object, check the momentum before asking and slowly pull it with feeling to the position where you imagine it should be (for example, the arm of an excavator or a front loader, a cab that rotates, etc.)
