There were several options for the download, and MANY of them produced no image that I could find on my Blender 5.1 app. Eventually I was able to see the transmission so very, very, small in the background, and managed to get the other parts of the complete engine (although trying to download the complete engine failed every time). I had to manipulate the images to be able to resize them to my usefulness. Whenever I tried to translate the objects, they would disappear as the author must have placed Viewport restrictions on the model. Other than that, the model was good.

Excellent

As usual, every part prints beautifully.
