Ekobots - Box-Cross Twist 3D Printer.

Converting my 10 years old Box-H to Box Cross Twist, no 2 level belts, no tilt/inclined belts, just a half twist in each belt.
After 10 years, I believe it is almost a different 3D Printer, in time I had changed, the eletronics, the power supply, upgrade the software, extruder and hotend, just the frame, the motors and the bed still from the original 3D Printer.
I do not know some one if already made a "3D Printer CoreXY" with a twist in the belt, if not it is the first and work like a champ.
For the "Twister" you need 2x (624zz) 13x5mm bearing with 4mm diameter hole and long m4 screws nuts and washers.
