A Generic Bulldozer, based on the Cat D7E blueprints. Modeled in Fusion 360. I haven't had the time to print it yet, but It shouldn't be a problem.
Any piece need supports, just rotate them according to the preview picture, there is also a .stl file "Bulldozer complete" that has all the pieces in the right position.
Updated: I have printed the model, it looks great! just be realy carefull with the tiny hydraulic cylinders.
Tips and comments would be much appreciated to continue modeling more machines.
