The model has to be scaled for me 40 % works great (~200 mm width).
For the right and left panels I used colorchange at a specific height. Look in the slicer it works pretty well! The connection has a snug fit maybe a little droplet of super glue would be nice.
The tires are mounted by M3-screws. By implementing a M3 washer and fixing the screws gently, the tires can also rotate ;-)
The trailer coupling can be fixed by super glue. I did not use any because I like the up and down movement of the coupling.
I also attached the .f3d file for some mods please feel free! The open windows and holes in the sides and roof can be filed again. I use them to fix on a ballon for the wedding present.
The author remixed this model.
First of all, thank you @Chameo for doing such a great work! Based on the design I made a reconstruction, made it demountable and implemented tires.
