Overall I'm happy with how this model turned out. There was a fair amount of cleaning to get the raw model ready for primer. I shot a nice thick coat of white primer on one of the wagons tonight, before I snapped these photos. The other wagon with the folded auger is not yet primed, but dry after the solvent bath. A nice coat of blue paint, and some white stripes around the top, and this grain cart should be ready for work. Now I just need to start working on that combine I was thinking about.
This is my first of likely many more farm implements to come. This addiction to 3d printing is my strongest yet. I have no idea how far this will go....
Here is a good illustration of how I designed the auger to be in either a folded or extended position. The wagon on the left is unpainted, while the wagon on the right has been primed. I designed the wagon as a base, separate auger, and separate tires, for easier painting and assembly.
