Use ABS plastic. I made mine with a diameter of 0.4 and a layer height of 0.2. It's best to run the file as one continuous piece. Be cautious when removing the round platforms from the arch. Use supports for added stability. After printing, process the handle of the lock with sandpaper to facilitate smoother insertion. Two M4 screws secure everything together. You can customize the edges of the rotary wheels by drawing any icons, letters or numbers you prefer.
