My apartment door is plain and boring, and given its number, I couldn’t not make this joke. I used Proofgrade thick draftboard, PG cherry and walnut veneers, ceramic magnets, and self-adhesive felt. The whole piece is sized so that the peephole is the correct proportion for the center-punch in Andale Mono’s zero. A kerf of 0.007" worked perfectly; the veneer almost snapped together.
Please forgive the potato-quality photos, the lighting in the hallway is pretty terrible.
I didn’t take a photo of the draftboard backer, here’s a screenshot from Fusion 360. There’s self-adhesive felt covering the magnets on the back-side just in case they work loose from the board.
I didn’t get the large veneer perfectly aligned with the underlying draftboard. In retrospect, I should have made an alignment (weeding?) jig by cutting a larger rectangle around the design in both the board and the cherry veneer. Then I could have clamped and adjusted the alignment before committing to the adhesive.
