Replacement interior plastic brace/bracket with screw holes for XB12?

@j053 . We would have to see what this all looks like. Looks like 2 of the screws go into extension “legs” from the battery case and two go onto some plastic fittings on the main board. We would have to see what this all looks like. Parts are not readily available so you would need to either purchase a broken speaker and harvest the parts from that or see if anybody can do some 3D printing for you.

Post some good pictures of where the crack is and which bracket you are referring to, with your QUESTION. Adding images to an existing question That way we can see what you see.
