So here are the printed parts for Z belt relocation kit that i am now discarding..



Of course I keep all the original parts that came with the printer so no matter what I can always take it back to its original state. Here is the backside of my Black Widow with a hybrid Dual Z mod..



And here we are frontside and powered on..



So instead of buying another 1.8 degree stepper motor matched to the one I already had for the Z I decided to order a set of 0.9 degree stepper motors for X and Y. The install was simple but this is a resolution increase for my printer. And I used one of the factory X or Y stepper for the dual Z as it was matched to the other one.
so obviously I have some changes I need to make in marlin for all this to work properly.
