Do you think assemblers are for suckers? Do you want to pack everything into one assembler because that's just efficient? Well say no more fam I've got your back! The Chesterizer is the all in one solution for all your chest needs. Just set some values conveniently split across multiple locations and away it goes. It's like magic!
I have built something very like this and fluids are a huge pain.
Thankfully they can be filtered now, but its a mess.
Mine relies on the network, the design needs 2 roboports to get requests and contents without them intermingling. I have a Quality buffer chest and conditions to do the same thing shown here. It's input and output, so things like gears and cables are available as soon as they're crafted.
I then have a second buffer chest requesting all the different fluid things that are produced the more traditional way, sulfur, electric engines, and the like, and its input-only.
There's other details, but the space is tight enough that pumping in 1000 sulfuric acid (since I'd be getting it via underground pipes) for a few blue chips isn't worth it.
I'm sure there's a better implementation than mine though.
