Simple Rotating Locking Cabinet Door Latch

I designed this simple locking mechanism for my cabinet door. I didn't want to screw or glue anything on the outside and, since there was a small gap, I figured I'd use it to my advantage.You will need an M3 nut which fits on the inner side of the latch, an M3 15mm screw to fix the rotating knob to that nut through the latch, and finally a wood screw to fix the latch on the inside as shown in the photos.I used a small round white sticker to hide the screw after installation.
