Got the tender shell cut in 2, playing around with options for the 3.5" extension. One is to get another similar shell, and cut out a piece the length I need. Only problem with that is both the cost of another shell, and cutting it (2 cuts), which is a pain. The other option is to print the piece I need. In theory, a piece of cake, except it's pushing the size limitations that I can currently print at. I can supposedly fit it (just), but that close to the edges, print quality may suffer. Of course, once the new printer gets here, that won't be an issue, but it's not supposed to ship until January. In the meantime, I've modeled the piece I need to add...
Printing out the top and one of the sides separately so I can just size and rivet placement...
