This looks like a job for a 3D laser printer. Since I now have some time I'll give it try based on the dimensions above. I can import the drawing into Rhino6. Then created the 3D model to then print.
Alan, that would be great to see! Please post photos of how the 3D printed cab turns out. Your 3D printed cab would save a lot time and steps for others that don’t want to build a cab from scratch.
