;D
Wasted most of today on this. The missile was pretty simple, once I'd worked out some scale drawings (not easy - there are surprisingly few GOOD profile shots of the missile). A few more bolts to add, but it's mostly done. I know, the fins look kinda thick, but that's actually .3mm, the thinnest that can be and still print.
(here before adding the rail hangers)
What killed me was the triple launcher. It looks so simple, yet the geometry is ridiculously complicated. I spent several hours trying to sort the contours at the back, before realizing I had fundamentally misunderstood the shape of the thing. Which meant re-doing a whole lotta work. It's still not 100%, but it will be easier to refine a printed master than try to calculate all the angles (really, I'd need to take a protractor to an actual launcher to be able to sketch it properly).
You can also see the now-added rail hangers. They *should* actually slide into the rails.
(though I just realized, I've got to check the clearance with the triangular lump at the front... note to self.)
The only other big thing left is to cut the stub pylon. Anyone know the correct angle of attachment? Have any reference pics to share? Looks like the fronts hang shallower than the rears.
Oh, and as an added bonus for the Americans in the crowd:
