X belt attachment for Anet A8 with better belt fit - no glue required

This is a remix of the x belt attachment which I like most by Simhopp with a better belt fit. The belt attachment by Simhopp is a really nice design, but I lost the belt during printing. After that I used glue for a second try, but after a few prints I lost the belt again. This is the reason why I remixed it. In different to the original design, I shrink the dimensions of the belt holder. With this remix you never lost the belt also without glue. Press the belt into the rabbet by using a flat screwdriver and you are done.

You will need six M3x18 screws for mounting the part properly to the printer.
