Base vehicle compatible with "BRICK DUPLO"

The model is printed from PLA. My profile is at 10% infill and 0.28 layer. It is the so-called the most economical profile and the model still looks good. Feel free to edit it if you want. The wheels are not mine, they are downloaded from https://www.thingiverse.com/thing:3254963/apps.

EDIT: I am adding a link to the wheels from one of you. I like them very much <3. https://makerworld.com/models/607387
