Remixed version so it can fit Ender 3 models.
Angle bracket to be mounted and add more vertical support, since i didn not want to try my luck with metal screws under the GTR, i made guide pins and glued the bracket to the back, and a T-Nut to bottom extrusion. Holds with no issues.
Cables best fit in holes (if you look on the bottom side from left to right)
Display cable goes also from the bottom side, in a little notch.
All stock cables fit, but you will need to move LCD to the left side, or buy longer cable.
Fan hole is centered above drivers, it fits 60mm fan.
I did print already modified version, you can spot little differences, then later updated designe after i assembled the board and found some weak spots.
