This is a bracket that keeps the bed's ribbon cable away from the print area, and additionally can help keep the cable from peeling off of the heating pad. It is meant to be detachable, however there is a screw hole for permanent placement on the bed frame if desired.
This Print worked perfectly with my bed and hopefully works well on your model.
I designed this because i noticed my ribbon cable was peeling off from the bottom of the Heating bed and was exposing the wiring soldered terminals. I also made this because i notice the ribbon cable it had gotten in the way of a print when i was printing a big project.
