Lego Duplo Train Car Roof

I love the [Lego Duplo Train Car/Wagon](https://www.thingiverse.com/thing:4086921) by [joesf1979](https://www.thingiverse.com/joesf1979), but I was not all too happy with the roof. I had a lot of trouble removing the support and I did not like the built-in brim. Most importantly the roof did not connect tightly with the wagon. So I redesigned it. My version of the roof is completely solid, easy to print and requires only limited post-processing. Besides it should connect tightly with the rest of the wagon. For the case it connects too tightly I have included the Freecad file. The model is parametric so you can tune the most important dimensions by changing values in the parameter table. Have fun and let me know if it worked for you! Feel also free to send me changes to the parameters. The current set worked for me, but is most likely not optimal yet and may depend on the printer model/settings (even if properly calibrated).
