@Tim_Rastall - I blame it on having spent way too much time with the in-house machinist who had a lot of things to say about amateur prints! (Mine included.) 
This is something that would look printed poster-sized and put in a frame.
@Joseph_Chiu , stuff I’d like to have poster size on my wall would be drawings of some of the hardware from NASA’s Apollo program. Quite a lot of that could cover a wall with one drawing. Come to think of it, some of that may be available at the National Archives. I once looked into original drawings of the North American P-51 Mustang, and they had them on microfilm for something $50 per roll. (Several required for the whole thing, of course, and a waiver saying you promise to not try to make a plane or any part of anything that will fly.) Then I’d need a way to scan the microfilm, and then a big plotter…
@Liam_Dewhurst the heatsink is quite different on the v5 Bowden version. The heater block has slightly different hole positions too.
