The original enclosure was cut from 1/8” plexiglass and included three openings in the front to adjust the time. After a few trials, I gave up trying to reuse the buttons/posts that came with the clock and got rid of the openings. I also tweaked some of the dimensions and re-cut the box in 3/16“ material.
The final version of the clock has a toggle switch to dim the display (it is rather bright) and a gap in between the face and bottom panels to adjust the time with a jeweler's screwdriver.
