Good luck and welcome back. I actually thought you were ready and forgot all about us. Anyway, hopefully you learned something from the discussions before and not made the same mistakes and miscalculations. One thing though... I still think you would have been better off with the 16mm stuff and the 20mm rails and should have let Jazz fix your issues, even if you'd had to pay for some of his services. 12mm rails are in my opinion too weak for a CNC. I think you will not get the rigidity you hope for.

In any case, ugly or not, it does no matter unless you make it for selling. One of the beauty of DIY is that it's OK if it looks like it was "home made" by amateurs, not factory made by professionals. If it works, it works. The beauty of things can also be the fact the "I made this..." so you can be proud of it, even if it is not winning a beauty contest. Making it useless is in my opinion worst, especially after all this fuzz about it, and especially in the second round. Hopefully you will be able to use it somehow, but my guess is that it will take a long time before you can make your first cut. Waiting for the parts is just the beginning of the process. In the meantime, you can start designing the electronics and all the rest.
