Here are the printed parts assembled as shown above.
I was having an underextrusion problem with my printer when I printer those parts, it was very intermittent, some smaller parts would print fine but other parts would not. I finally resolved it and now I am back up and running properly.
As it turns out underneath where the green crossbar is located is an "I" beam that supports that plate, I have decided to add it to the assembly as it adds additional strength to the bogie. pictures to follow.
