...BUT I still have doubts. More lamentations below.
Here you see the body section, the lead-filled nose cone and the mostly hidden 24mm motor mount. I didn't research what the bottom is supposed to look like but I liked the disc you see here. This is just barely scale-like anyway.
The last big thing is the nozzle. The paper one from the paper model won't work as I'll need to adjust the base diameter considerably.
After dry fitting this together my estimate of its Psuccess has dropped around 15%.
