motor mounting bracket

I saw that the motor bracket from Alfawise U30 is only a little sheet of metal. Also i saw that the force on the motor axis are too high. The pulley is placed at the end of the motor axis and torque the axis exaggerated.
So i design a new motor bracket with lower torque on axis and you can use the original screws!
The Pulley distance from the Motor is 1mm, you can see this on my pictures.
The Bracket has a great strenghs and no spring options like the original red sheet metal.
The torque force reducing at seen in the example picture.

Update:
I added "Motor-Flansch-V4.stl" with 2mm more Space to the Printer-Side to mount Motor damper.
I hope this works, i didn't use damper - please Mail me to report.
