I built the Rawen version (Repaints by bgt01) but i also found addon parts by Falwin. Falwin had done a redo of the container that was a little shorter and more in line with the Franz manual dimensions. - I have no idea where i go the files but i can share on PM if you wanted them.
Tips and Observations - It was relatively easy to build, the only thing that was "tricky" was the Nacelle Pylons - getting the angle was flipping hard, one of mine is too close to the container compared to the other but hey! A solution might be a piece of wire in a U shape inside the saucer and hanging down.
