After getting the Graber ATX 3D printer frame, laser cut using the latest release from github first problem was one of the bolt hole from frame side is out of alignment with the connecting piece. that was an error in the file not cutting.
My other issue was the y axis motor has single wood mount, is held on with a little screw
It is really quite flimsy, seemed skewed on an angle when tightened.
If I had known about this before cutting could have fixed them anyway.
This is my attempt, at reinforcing without any cutting or drilling. I may add an anti-twist modification for the rear of the motor.
May require a file, to remove excess material.
