Endgame red circuit build that outputs a fully compressed red belt. Design is tileable.
Inputs: 34 copper plates per second, ~43 green circuits per second, and ~43 plastic bars per second. The outside input lines should be half green circuits and half plastic. The next two inner lines are copper, which feeds copper wire assemblers.
Since the design is symmetrical, each half belt conveniently side-loads onto a single red belt for output.
