I'm sure people will have far better designs, but I did come up with this layout just now for producing destroyer drones. It produces enough components to keep the destroyer assembler always running and can be done with entirely yellow belt. I'm not entirely happy with the top/left parts which were mostly tacked on to make it work, but I find the main bit with the hexagonal assembler pattern really pleasing. It's certainly far better than all my previous designs, which involved producing the ammo, defenders and distractors in three separate assembler lines with their own input/output belts.

I must give credit to MangledPork's excellent video series as in one of them (I think it was in his No Crafting challenge) he showed off the idea of running belts underneath the assemblers they supply, which I'd never seen before, and I've used that liberally here!
