Odd shouldn't be hard to do and the plastic quality is fine, I took mine to a plastic fabricator (actually called plastic fabricator) here in a industial area of Adelaide, they had no problem doing it no questions, but I didn't specify anything to him, he just knew It wouldn't be seen and he did it in white plastic. .... I only trimed the back/side edge of it which is black plastic and he plastic welded a white section in, I just wanted it to seal the unit, if It was a visible section I wouldn't have accepted it white. It cost $20 each from memory (so $40).
