This is a fire truck toy with a ladder and two back axles.Other than the two back axles, it is basically the same as this one here:https://www.cgtrader.com/3d-print-models/games-toys/toys/fire-truck-with-ladder(that's why the assembly video and the photos are with that model)
There is also an additional cabin version, which has screw holes in the front for attaching two screws as front lights.
Fully printable, no support, one material/colour printer. All parts should fit on a 20x30cm print bed (the ladder is the longest part).

The tolerance for pieces that need to fit tightly is 0.1mm,for pieces that need to allow movement (like screws and axles) 0.3mm or more.
