Here it is, with a twist. I decided to try attaching the fencing only to the upper tray. This simplifies a lot of things from the printing perspective, and it was a suggestion that came from a friend who was over looking at my reloading room yesterday. Since I had the pieces, and printing the flat sides was easy, why not try it.
Watch the video and give me your feedback (please ).. Really, I think the only downside is the possibility of forgetting the pieces aren't all attached and dropping the bottom tray.
You'll see that dropping cores is still the biggest problem (they're still catching on the lips of the jackets). I know how to fix that, but this copy doesn't have the fix. Even manually having to place many of the cores, it took just over 4 minutes. You'll also notice that it's the jackets themselves that are keeping the upper & lower trays aligned. I put 4 jackets into the corners manually to pin them together when starting.
