Ender 6 Linear Rail Y

Used the remix of the design made by vampyrex13.
The main change is that the idler holder connected directly to the X 2020 profile with stock screws.
The connector is between MGN12H on Y axis using M3 screws and M4 T nuts on X 2020 profile.
I used slide in spring nut block closer to the center of the X 2020 profile, and T nuts closer to the edges of the X 2020 profile.
