I did not like the ribbon cable on the CR-10S Pro sticking out into my work area so I designed these so the cable would take up less room. I had to open the bottom of the printer and loosen the clamp to pull out a few extra inches of ribbon cable so that I could get full travel on Z axis. The reason for this is adding these brackets will negate some cable length, so dont foget to do that.
You just need support from build plate, placed in the orientation shown in the screen shot.
If using Cura tree supports worked well for me.
