With the approximate 16.5 deg. overhang in printing that opening, there is a little bridging involved. I did not really look at that opening that closely last night, but I have printed a completely vertical overhang before & it drooped a little at 1st but final part came out ok. That was when I did a test print of a one piece version of the LCD wood panel with the bottom LCD opening at the top of the print. If the overhang does not print well, you could try adding some support. I prefer not to print support if I can help it.

What type of plastic were you printing with, ABS, PLA, PETG, ...? I am really liking the PETG plastic.
