This Purple (Production) science blueprint is tileable for 0.16. (i.e. No Assembler 1 production). Iron is used the most so it's on the outside which makes it easy enough to run a parallel iron belt to supplement longer lengths.

Usages
- Iron Plates - 8.0/s
- Bricks - 5.7/s
- Steel - 6.3/s
- Green Circuit - 1.1/s
- Red Circuit - 2.9/s
- Lubricant - 8.6/s
Note: It was late when I did the usage calculations so I'm not very confident of the numbers.
I used constant combinators to show where resources are to come in with the exception of the bottom belt which is for iron.
