Single assembler bot mall, place it and input what you need on the constant combinator, it will slowly do its thing.
-Requires bots
-Do not exagerate on item numbers, it might overflow the passive provider chests and clog it up
-As long as you have storage chests the requesters will not clog
-Want more assemblers working? Copy/paste the one with its chests (no combinators) and link the green wire to it.
