I really liked the new wiring shroud on the RevE M2 with the exposed connectors - making fan and hot-end swaps quick and painless. When I went to the dual I missed those exposed connectors.
So I used the model for the single shroud as a starting point and made one for the dual.
I need to swap the extruder and heater connections on the left side and make a few other minor adjustments to the design before it can go public, but I installed Rev 1 tonight and it worked out pretty well.
