Here's a quick shot of my workbench with completed printer. It's been a journey through three massive iterations over the course of two years but this one works like a charm.
Smoothieboard/MGN12 Rails/Misumi Extrusions
Edit: please critique.

Be A Con...has a mad ring to it 
Didn't see any of the previous versions of this, how come you went for belt on Z, anything there to stop it falling? It needs more lights

@FA-MAS the plan is to release all the files with instructions on Thingiverse. I'll update when that happens.
@o_lampe the bowden tube is just because that's what I had already
@Mecha_bits the belt drive system was preferred over a leadscrew because it's easier to mount accurately. Way easier.

So as it is close to the first release, How are you gonna handle the position of the electronic and power supply ? Cable management and heated bed ? And, why a Dual Z rail, one would be sufficient ?
I think I will build one as soon as it is available
P.S. How do you ensure the belt are evenly tensioned ?

Electronics will be located under the bed. Glad to see such interest! It should be a relatively inexpensive build because it will work with any electronics setup and the extraneous cost is the MGN12 rails.
I don't think belt tensions is as crucial as it is on say, CoreXY because each axis runs independently.

I was wondering how/why you decided to stagger the carriages on Z probably a good choice, more support, easier to fit, better for your 2020, I cant remember why i decided to put mine inline, probably to save on Z height, and probably because I was just thinking linear, straight lines....
,
Basically cause they wouldn't fit next to each other on the 2040 rails lol.
I knew there had to be a reason

Is it the weekend yet? 
This may be one of those interesting designs where the most economical way to build it is to buy a full kit for a different printer, then just use those parts as the vitamins for this one. Sometimes the generic 2020 i3 kits or the like can be a pretty good value for the components, and you save a lot by buying all of the items together at once instead of shipping a bunch of random parts separately from different sellers. Being a cantilever design, it also could be much more forgiving for tolerances on some parts, such as having random/arbitrary lengths of the extrusions, or not requiring 8x of them cut precisely to keep a cube square.

Ahh, yes, I had forgotten that most of the inexpensive kits are based on rods instead of rails. And once you get to a kit substantial enough to use linear rails, you're going to be spending quite a bit more, and still not necessarily going to get four of them like your design requires. Ok, nevermind on that then.
