The main crane has taken a few evenings work to design on CAD,and the final files made ready for 3D printing. The main jib took around 9 hours to print and the control section only took 3 hours, but I am always amazed with the results from the printer.

As you will see the image below shows the cad drawing followed by the finished model.
